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!
