Inspector Portable Carbon Monoxide Detector with Visual and Audio Alarms – Waterproof Digital CO Detector for Personal, Ambient, and Combustion Monitoring

This little c/o detector is fantastic! I have one in my house & I put one in my car to make sure it’s safe & bring it with me on vacation for the hotel room. Works on low levels which is so important.

This is an excellent product. I frequently use a propane cook stove in a small area and I need to monitor the CO. This is an actual measuring device as well as an alarm. I have tried to use home CO alarms and the were not useful, even the ones that have some digital readout. I paid over $100 for another brand of CO sensor that was highly recommended for pilots of small aircraft. It worked, but it didn't show readings until an alarm level was reached. This Sensorcon unit starts reading at 1 ppm. Listed as accurate to +/- 2ppm, I have no reason to doubt that. I don't have equipment to test this thing for accuracy but after several years of very frequent use, I am convinced that it works reliably and is likely far more accurate that my use requires. I was not aware that a freshly opened can of coffee grounds contains a high level of carbon monoxide. I open a can of coffee in the vicinity of my unit and its alarm started beeping. I didn't know what the cause was, but eventually I put it near the coffee and the reading went above the upper limit of the device. It seemed to damage the unit. I could not get it to work again, but the next morning it seemed to be functioning normally again. Keep it away from car exhausts especially when the car is cold and just being started, and keep it away from freshly open coffee grounds and you will be very happy with this CO sensor.

Good product. Used in a canvas tent and for every day use. Tested it by breathing on it and it almost instantly gives u a reading so then I tested it by putting it by the exhaust of my motorcycle and it went through the roof. Very accurate. A few days later I used it when using a wood stove in a canvas tent and it gave a warning during the night when the draft changed and smoke was coming into the tent, super helpful. I typically hang it up in the tent but if I had it laying beside me I wouldn’t be too worried about accidentally shutting it off because of the power off countdown safety feature. Rule of thumb though, never fully depend on one of these detectors because you could very well sleep through it if you are a heavy sleeper. It’s best to not have a fire on through the night but if you do, this product would be a great add on to any outdoor pack.

I like this product. It seems to work easy enough and be decent. However, there are less expensive CO monitors that do the same job just as well. For the Expense of the item, I would likely buy another item next time.

I use this in my airplane and it works perfectly, turning it on/off every flight. With irregular use, and approx 400hours of on time, the battery lasted me about 2years and 8 months. Battery replacement is easy. 1. Unscrew 4 Philips screws in the bag 2. Pull apart the casing 3. Replace with a CR123A 3V Lithium Battery
