I bought this detector because I was concerned about a diesel heater that I had installed in my sailboat. It showed 0 (zero) whenever I checked it so I was now concerned that this detector, like my other two, might not be working either. I put it near the exhaust of the heater and it showed approximately between 30 and 70 PP. After running the heater for a while it went back to zero. Still not sure if it was working properly I tried putting it by my car exhaust immediately after starting the car. At one point it read 1000 PPM, the maximum, but after the car ran for a while it went back to zero. So it seems to work very well. I shopped around for this unit, so I know it would be hard to find something better at this price. Seems to be very high quality too.

Priced so low I thought it would be junk! Instead the CO detector was very useful in identifying sources of CO. VERY USEFUL AND EASY TO USE.

I love this CO2 detector. It's a great tool for checking CO2 levels. I encourage my techs to use it all the time as part of our basic pre-season tune-ups.

Definitely works tested on my car exhaust pipe

I was feeling sick and couldn't figure out why, so I brought back out my air quality tester (that is now in the garbage), and it signaled to me that the CO was extremely high in my room, scared the crap out of me, got this overnighted to me, this thing is awesome, well built and seemingly very accurate.

Appears to work as expected. Reports zero when in clear air. Reports over 300PPM when placed about 4ft from UTV exhaust (it's a 20 year old gas engine).

Easy to use, just read the directions. Seems to be accurate. We're still alive . . .

5 out of 5 stars
