The QRAE II Monitor is Available in Three Configurations:
- 020-1111-1A0 LEL/O2/H2S/CO Diffusion Alkaline
- 020-1111-0A0 LEL/O2/H2S/CO Diffusion Rechargeable
- 020-1111-2A0 LEL/O2/H2S/CO Pumped Rechargeable
All QRAE II Monitors feature a rubberized exterior to cushion a rugged housing that has an IP-65 rating for water and dust resistance. The large graphic LCD screen is automatically backlit in dim light, displays the readings from all sensors at all times, and can even be flipped electronically to be readable when hanging on your belt.
An additional metallic barrier gives the QRAE II the best EMI/RFI resistance in its class. This immunity from electromagnetic and radio frequency interference is a big deal. Many of the cheaper confined space gas detectors on the market will react (and even go into alarm) when standard industrial radios and walkie-talkies are in use nearby.
Just 2 buttons control all functions, and they can be pushed even while wearing gloves. The warning alarms are comprehensive, with a loud 95db buzzer, bright red LED lights flashing on top and a vibrating alarm to make sure you get the message even when working on a noisy work site.
The QRAE II includes 64,000 data logging points of storage capacity for download to a Windows PC (a recharging cradle is required for this feature). Your choice of alkaline or Li-ion batteries, with either one giving up to 14 hours of continuous operation. CSA intrinsically safe approvals in the US and Canada: C1, D1, Groups A, B, C, D, T4 and European: ATEX II 2G EEx ia d IIc T3 and T4.
The QRAE II is an extremely affordable, hard-working, and easy to use gas detector. The QRAE II works well in many applications including refinery work, oil rigs, fire fighting, confined space entry, maritime industrial work, utility companies, gas plants, military, environmental and safety engineers, HazMat first responders, and industrial safety engineers.

QRAE II Video Transcript
Hi, I’m Chad and welcome to PK Safety. Today I'm going to show you why our customers have made the QRAE II 4-gas monitor from Rae Systems one of our best-selling and most popular gas detectors for confined space entry.
00:18 The QRAE II comes in three configurations, each with their own advantages. But by far the most popular version is the pump model. When equipped with a supplied hose attachment, the pump allows a worker to safely sample the air before entering a confined space.
00:30 Unlike several gas monitors on the market, the QRAE II has a built in operating system, along for adjustments at any time without the aid of a computer. This provides an added layer of convenience when switching job sites, or when you simply want to change a setting.
00:44 Two large buttons control all functions, so adjustments can easily be made on the fly. The monitor's comprehensive warning system provides a vibrating alarm, 95-decibel buzzer, and flashing red LEDs. So you'll always be alerted of danger, even when working in a noisy environment.
00:58 The QRAE II from Rae Systems is an affordable, hard-working, and versatile 4-gas monitor and it may just be the perfect tool for your next confined space entry job.
01:07 Thanks for watching. And as always, if you have any questions, feel free to give us a call, or visit us at pksafety.com.
RAE Systems QRAE II Confined Space Gas Detector 020-1111-2A0 - Calibrating Your QRAE II
Calibrate QRAE II Video Transcript
Hi my name is Ben and welcome to pksafety.com. Today we're gonna show you how to calibrate your QRAE II Gas Monitor in seven easy steps.
00:13 The first step in calibrating your monitor is to make sure you're in a clean air environment. Make sure there's a charge in the battery in the monitor. You're gonna take the cylinder of gas and also the regulator and you're going to attach the two. It simply screws in, finger tight is fine. Like so.
00:33 Step number two, turn the monitor on. Press and hold the power button for a second, and allow the unit to warm up. Once the unit's on and running, it should display all four gases that it can detect. First of all, we're gonna do a pump integrity check. Simply take your finger and put it over the end of the pump. The pump should stall and go into alarm. Acknowledge the alarm by pressing the "Y" key. Now we know that the pump integrity is good.
01:05 Step number three, we're gonna enter the programming mode. To do this, we're gonna hold down the "Y" key and then hold down the "power" key. The next screen will bring you to a password screen. The password is sent from the factory at "0000," unless it's been changed by the previous user. To get to the "OK" button, press the power, you move the cursor over the zeroes, and eventually it will get to the "OK." Once it's on the "OK," press the "Y" to acknowledge.
01:32 Step Four, the unit should display "calibrate monitor?" You do want to calibrate the monitor, so you're gonna press "yes" to acknowledge. The next screen will bring you to "fresh air calibration," again with a question mark. Yes you want to calibrate in the fresh air, so you're gonna press "yes." It takes thirty seconds, there's a countdown panel on the screen, don't press any buttons while it's doing it, just sit and wait.
01:59 Step number five, the screen will say "multiple sensor calibration?", that's what we're gonna do next, so hit the "Y" key. The "OK" will be flashing, on the left hand side, you'll see all four gases displayed. We're gonna use the standard core gas, so we're gonna calibrate all four sensors at once. When it says "OK," you're gonna hit the "Y" key. Next step, it'll ask you to apply the gas. Make sure you have the gas and the regulator ready, because you don't have much time to do this. I'm gonna hit the "yes" button over the "OK," and it says "apply mix gas." Connect it to the monitor, gonna screw finger tight. Calibration takes sixty seconds, there's a countdown timer on the screen, just sit and wait again. When the unit says, "multiple sensor calibrated," you can remove the gas.
02:49 Step six, now that the unit's calibrated, we're gonna head back to normal mode. To do this, hit the power button, and eventually you'll see a screen that says "back?" You're gonna hit "yes" on the "back," it'll take you to the previous menu as well, just follow the same steps, press the power button until you see "back?" and then hit yes. Now you'll see "back in normal operating mode."
03:10 Step seven, we're gonna do a quick bump test, just to make sure all the sensors and alarms work. To do this, we're gonna reconnect the gas to the monitor, and we're making sure all the alarms go off, the vibrations, the flashing lights, and the noise, and that all four sensors go into alarm. You can see this by looking on the screen, it will flash low or high. So we'll connect it, all the alarms have gone off, all the sensors are registering, we can remove the gas, I know that all the sensors work, that's the bump test over. The unit will stop beeping and alarming, just give it a few minutes for the gas to disperse from the sensors.
Thanks for visiting pksafety.com. Remember that you can always send your gas monitor to us for repair or calibration. Thanks for watching.

Popular, Easy-To-Use and Durable Review by Rick Pedley, Product Expert
"The QRAE II has been a top seller for years. In particular the rechargeable version. Just leave it on the charger, and you are ready to go anytime. The alkaline version needs some warm-up time if the batteries are drained or left out of the unit.
Our service techs will confirm that this is a trouble free instrument. We seldom see them in for repair, and do not sell many replacement sensors, which speaks well of their useful life.
With the internal motorized sample draw pump, this is truly a confined space gas detector. All the features you need, at a very reasonable price."
Simple to use
Low cost to own
Alkaline version could be better

Fast delivery Review by Tony
I ordered this monitor and got it the next day. Could not believe how fast it arrived! Had to read the instructions twice to understand how the two buttons work but once past the initial confusion it is easy to use. Have used it twice for confined space work. Glad to have it by my side. (Posted on 3/29/2013)

When used in the correct manner these monitors can make a safety plan OSHA compliant.
The CSK2 does include everything that comes in the CSK1 kit. What the CSK2 adds is a cylinder of calibration gas and a 0.5 liter per minute (lpm) fixed flow regulator. This allows for calibration and bump testing of your instrument.
Yes, it works for multiple applications. It is just labelled for confined space because it has a pump to draw the air sample (before you enter the confined space). It works great anywhere you need a 4-gas monitor.
RAE Systems hasn't informed us that the QRAE II is being phased out, but we assume it is. We'd say go with the QRAE 3. It's the future direction for RAE Systems.
The QRAE II can pull from a maximum distance of 65 ft. Remember to allow about a second per foot for the sample to arrive at the monitor when pulling from longer distances.
