Sporting four gas sensors for detecting hydrogen sulfide (H2S), carbon monoxide (CO), oxygen (O2) and the LEL of a variety of dangerously combustible/flammable gases, the GasAlert Max XT II portable detector also features an internal pump for remote sampling. It comes calibrated with a fully-charged battery, and is ready to use right out of the box.
The GasAlert Max XT II is a handheld gas detector which displays levels of all four gases on its bright, backlit LCD screen (which also shows you battery levels and pump activity). It allows you to clearly monitor your environment no matter how dark and dingy your confined space may be.
A selection of alerts and alarms keep the worker aware of any dangerous levels as the gas analyzer constantly monitors the environment. Bright alarm LED lights, vibration options, and a 95dB alarm ensure you get the message. The GasAlert Max XT II also has an optional confidence beep, which tells you the device is operating and fully functional. Alerts for the GasAlert Max XT II are available for Short Term Exposure Limits (STEL) (5-15 minutes), Long Term Exposure Limits (LTW; ~8 hours) as well as high/low levels for each gas.
Designed to be solid and durable, the GasAlert Max multi-gas detection unit has concussion-proof housing, as well as an IP66/67 rating for water-resistance, meaning your unit should continue working well throughout its lifetime. The internal sample draw pump is easy to maintain, with both moisture and particle filters protecting it, which are easy to monitor (via a filter window) and change.
Many folks operating gas monitors work with protective gloves on. BW Honeywell's entire range of detectors feature simple one button operation: one single large button designed to be operated with a gloved hand, making it particularly easy to train your staff to use this portable gas detector.
The GasAlert Max XT II is compatible with the MicroDock II for recording your readings throughout a shift, for charging the kit, and for altering settings for alarms and tolerance levels should your company require it (via the IR Data Link Kit found in the Deluxe Confined Accessory Kit).
Each GasAlert Max XT II unit comes individually packaged in a cardboard box that includes the 120V AC battery charger, operator's manual, CD-rom owner's manual, 5 spare moisture filters and 5 particulate filters, metallic scintered particulate filter (for end of sampling hose) and 2 lengths of (3 ft. length and a 10 ft. length) clear PVC tubing with connectors, double-ended screwdriver and factory calibration certificate.
Note: Calibration gas may be ordered separately. Due to HazMat regulations, calibration gas takes between 5-7 days to ship, and will not arrive at the same time as the monitor.

BW Honeywell GasAlert Max XT II Confined Space Monitor XT-XWHM-Y-NA - Diffusion vs Pumped
Pumped vs. Diffusion Video Transcript
Hi I'm Chad and welcome to PK Safety. There's nothing worse than purchasing the wrong tool for the job. So today we're going to show you the differences between diffusion and pump style monitors.
00:14 The most obvious difference between these two designs is the way each of these detectors sample air. The pump model has an internal, motorized suction pump, so you can draw in a sample of air from a safe, remote location. This makes it perfect for confined space gas detection. The hose can be attached to the pump, allowing a worker to sample the air from a considerable distance away. The pump does make the detector slightly more expensive and a little heavier, but if remote detection is necessary, it's the perfect tool for the job.
00:38 Diffusion monitors sample the air and detect changes in the atmosphere within their immediate vicinity, which means that a worker wearing a diffusion model has to come into direct contact with dangerous gases, before the monitor can detect them. Though not ideal for gas detection in confined space entry, they're perfect for open-air environments. Diffusion monitors are also much lighter, considerably quieter, and slightly less expensive than their pump counterparts.
01:02 Each of these gas detection techniques is suited to different needs. Choosing the right one can be the difference between life and death. With a slightly higher initial investment, the pump model insures safety before and after entering a confined space. Now that you have a better understanding of these two gas detection methods, you should be able to make a more informed decision as to which tool is right for your next job. Thanks for watching and as always, if you have any questions, feel free to give us a call or visit us at PKSafety.com.
BW Honeywell GasAlert Max XT II Confined Space Monitor XT-XWHM-Y-NA - Unboxing The GasAlert Max XT II
BW Gas Alert Max XT II Video Transcript
Hi, this is Rick Pedley and welcome to PK Safety Supply. Today we're going to be looking at the BW GasAlertMax XTII. It's one of our most popular confined space gas detectors. It has four censors and is used for confined space entry (think tanks, manholes, vaults -- all sorts of stuff like that). It has an internal sample draw pump and a bunch of features which we're going to cover. So let's take a closer look at this.
OK, let's take a look at what comes in the box. First, of course, is the detector itself, the GasAlertMax XTII. We get the wall charger, which plugs into any AC outlet. Also available as an accessory is the 12 volt charger/adaptor that goes in your car. And underneath, let's see what we've got here. We've got the calibration certificate from the factory, and the manual in hardcopy and DVD format. Then we get a screwdriver with five sets of replacement filters for the pump, as well as a particulate filter that can go on the end of a hose. We've got two pieces of hose. One three feet long, another 10 feet long and they have the connector on the end that attaches to the detector.
Now, let's turn the unit on. It's a one button operation. Just going to press here. The unit starts up. The screen now tells you the firmware version. Tells you that it's a GasAlert Max XTII. Asks me to block the inlet, which means I'm going to block the hole at the top where the air is being sucked in. This tests the pump. Now it says "Unblock inlet." Says "Pump OK." Next, it's going to tell me the alarm levels. These are the alarms for the time weighted average (TWA) and then the STEL. Then it's going to show me the low alarms. It displays all four. And the high alarms. Once again, displays all four. Then it runs through a self-test. Says "Self-test OK." It now shows me all four gases here, and it's auto-zeroing. This is important. Then "Cal Due." Says 150 days on this particular one, our demonstrator unit. Now all the gases are displayed. There's a little blinking heart down here in the corner. It's going to tell you that the unit is working just fine.
Hear that pump in the background? It's continuously sucking air across the sensors. This is going to give you a reading coming through the hose. Now, the hose, which we mentioned earlier, attaches right here at the top. Little connector -- very positive. Comes on, comes off very easily. You can put a wand on the end of it if you like. The other thing that's really unique about this unit -- I'm going to grab the included screwdriver here -- is that this plate covers the sensors, and the pump is sucking the air across those sensors. What's really unique here is that we can take that cover off. So I'm just going to back off this screw and it's kind of interesting… I'm going to take the cover off, and when I do, the kinetic switch says "Oh, there's a problem! No more cover on there." But if I press this button it says "Pump off." Now the pump is off, and you'll see that the four censors are now open to the air. This is now a diffusion instrument and can be worn on your belt. The pump's also not running, so the battery is going to last longer. This is also useful if something happens to the pump -- you can use it as a diffusion device and still have a perfectly good running instrument. Really interesting that you can use that.
Now I'm going to take this, it's just a little piece of metal -- it's just a magnetic switch -- and I'm going to put this back on here. I don't even have to screw it in. Once again, the alarm comes on. All it wants me to do is acknowledge it. Press the button and block the inlet to test it… unblock inlet… and we're good to go! It says "Pump ok!"
We can tighten the screw or not, but you can see: it's back at it!
BW Honeywell GasAlert Max XT II Confined Space Monitor XT-XWHM-Y-NA - How to Calibrate the BW GasAlertMax XT II
How to Calibrate a GasAlertMax XT II Video Transcript
Hi, this is Rick Pedley and welcome to pksafety.com.
Today we're going to look at calibrating the BW GasAlertMax XTII Confined Space Gas Detector. OK, so we've got the unit turned on. You can hear the pump running. We're just in normal running mode, just like it's warmed up.
So what I'm going to do is introduce cal gas. And I'll kind of cover what we've got here. First, here's a cylinder of calibration gas. This has all four gases in it: hydrogen sulfide, carbon monoxide, oxygen and the explosive gas, or LEL. On top, i have a regulator. Now this is a constant flow regulator and it puts out a half liter per minute. This is the one that comes in the kit and this one happens to be made by PortoGas. BW does use others from time to time.
When we turn this on, it's going to flow the gas through this tube and out the end, which we're going to attach to the instrument. So, the first thing I'm going to do now that I'm ready to go -- I've got everything here -- is press this button. It's important when you're doing this that you press and hold this button. So, I'm going to hold it in and hold it. And it's counting down. The screen goes blank, then it comes back up with "Cal 1, 2, 3." Now I can release this and it's auto-zeroing. Important that we do this in an area of clean air.
And now it says "Apply gas." So, first thing I'm going to do is turn on the cylinder of gas. The gas is now flowing. I take this hose, and I attach it with the quick connector. And immediately, the reading starts to rise. This is in response to the gas. It's going to come very close to what's listed in this cylinder. After a period of time, which is approximately a minute, the unit's going to self-adjust to the exact specifications that are on this cylinder. And this is the cylinder that they intend for you to use.
Calibration is a kind of interesting this. OSHA, if you follow the rules exactly, I think would have you calibrate this unit every day. Most of our utility customers -- that is, people who use these things day in and day out -- they may go for a week or a month. But if you're the type of user who only fires up the instrument occasionally, let's say once a month, or something like that, I would suggest that you strongly consider calibrating it every time. This is a life saving instrument, and really the only way to know that it's working appropriately is by putting cal gas across the unit.
Now, this is going to take about two minutes as it goes through its cycle here. This regulator flows at a half liter per minute, so we're going to use about a liter of gas. This cylinder, the one that comes in the kit, contains 34 liters. You should get about 30 calibrations out of this cylinder.
[One minute later]
Alright, calibration is done. We're all set there. Now it's going to tell me to remove this thing -- essentially it has gone into alarm because the cal process is over with. So what I'll do now is just remove this hose off of here and turn off the gas. This is kind of important because this gas is ridiculously expensive!
So now the readings are going back to zero as the censors have been flushed with new air. We're reading zero across the two toxics and the LEL and 22.9 on the O2. The instrument is now calibrated and ready to go. The cal has now been reset on this as a countdown from 180 days. I don't recommend that you wait 180 days to calibrate this instrument, but that's the way the factory sends it.
That's all there is to it! Pretty simple! Thanks a lot!

- Good for Confined Space Review by Jason W.
I work for AT&T. We use these monitors daily when entering manholes. To my knowledge we have never had a problem with them. Easy to read display. Yellow case gets dirty pretty quick. Best feature is the pump so you can sample air before going into a confined space.

0voteA: There are only 2 parts that could be faulty inside the instrument. Either the screen is defective or the PC Board is damaged. If the unit is less than 2 years old it may be covered under the manufacturer’s warranty, exceptions are water damage or physical damage. I’ll be happy to check the serial number and confirm it’s still under warranty if you’re unsure. We’re a warranty service center here at PK Safety and can perform warranty repairs at no cost to you. In the even the unit isn’t covered under warranty we can provide you with and estimate to repair the monitor. When you’re ready to send the monitor please call us for and RMA number prior to shipping.
0voteA: It sounds like something did go wrong during the sensor swap. I suspect the screen came away from the main PCB at some point during the swap. There is a small, white, rectangular foam like piece that transfers the signal from the PC Board to the screen itself. It slots into an opening on the bottom of the screen and protrudes slightly. To the untrained eye it can easily be discarded as trash however it is needed. I suspect this piece has fallen out.
There are possibly a few other scenarios that may cause the same problem. I would be happy to talk you through the recommended steps. Please feel free to call us at 510-337-8880 for assistance. We’re a BW Warranty service center and will be happy to service your monitor if needed.
0voteA: The BW Honeywell GasAlert Max XT II has an internal sample draw pump. This diaphragm pump pulls air through clear Tygon tubing, usually supplied with the BW XT-CK-DL confined space kit. The rate of flow is approximately 1 foot per second. A 15 foot length of this hose would have about 15 seconds of lag before reaching the sensor. Once the sample arrives at the sensors, there is a reaction time to be considered. Industry standard is to measure the time it takes to achieve 90 percent of the final reading. This is expressed as T90, and in the case of the Max XT II, it is 35 seconds. The initial reading on the instrument will rise quite rapidly, but to get the full, true and accurate reading, we use T90. For our example of a 15 foot sampling hose, we could confidently predict 50 seconds for an ‘accurate’ reading. In practice, you should be very close to accurate in substantially less time.
0voteA: On start up, the CO, H2S and LEL sensors should be reading 0, with the O2 Sensor reading 20.9% in fresh air. The BW GasAlert Max XT II, with its internal sample draw pump, then pulls sample air across the sensors. The intended use for the instrument is in confined space entry, though other uses do come up regularly.
The LEL (explosive gas) sensor in the Max XT II will not function in an inert environment, as it uses a catalytic bead sensor, which requires oxygen to function. If this is the use that you have in mind, you will need to use an IR (infra red) sensor to measure LEL. This type of combustible sensor does not require oxygen to make measurements.
0voteA: We do have the GA-BXT concussion proof boot for the Max XT II available as a separate item. They are in stock.
0voteA: Most likely you need a new Oxygen sensor. If the monitor has been dropped or wet that would do it too. If the monitor is brand new it could be a manufacturing defect. 95% of the time a new sensor fixes the problem.
0voteA: Yes. The maximum length of hose for the Max XT II is 65 ft. Using a longer hose, allow about a second per foot for the air sample to reach the monitor.
0voteA: The regulator needed is the BW demand flow regulator. Part number BW01-REG-DF-1. Current price is $360.00.
0voteA: The GasAlert Max XT II comes with the following:
Manual (in hard copy and dvd)
5 replacement filters for the pump
One replacement filter for the end of the hose
One 3 ft. piece of clear hose with unit connector
One 10 ft. piece of clear hose with unit connector
0voteA: It sounds like there is a leak somewhere in between the pump inlet and the pump itself. First try replacing the filters if they are dirty the pump may be under too much strain. If replacing the filters doesn’t fix the problem it’s time to send the unit in for service. Here at PK Safety Supply we’re a factory authorized warranty repair center. Our typical turnaround time is just 24 hours and if the defect is covered under warranty it won’t cost you a penny! Please call today us to obtain an RMA.
