Rated 3.9 out of 5 by 9 reviewers.
Rated 2 out of 5 by I don't trust it I was using this for my home inspection business and it seemed to read 0 then when I would pick it up it would jump all over. 70-140 then 0. Didn't feel like I could put families health on the line with these results. October 14, 2014
Rated 3 out of 5 by Not high end but does the job This small CO digital detector does a nice job of taking a quick CO reading. We were having some issues with ceiling mounted battery operated First Alert CO detectors that were going off. We used this hand held unit to confirm that the Firt Alert units were getting wrong readings (or defective units). It's not fancy, but for the average user it does the trick. February 20, 2010
Rated 5 out of 5 by Product worked as advertised Exactly what I was looking for. This device is quite accurate. I use the tester to check for exhaust leaks on diesel engines. March 27, 2013
Rated 5 out of 5 by Good instrument to check CO in home We used an indoor rated gas heater in the basement during the cold weather and eventually a home CO monitor alarm triggered. This did not give the CO concentration but just that it had reached a dangerous level. We vented the house but was not sure that all the CO had been removed. We used this instrument to sweep the house and check that all CO had been removed. March 5, 2014
Rated 5 out of 5 by works fine It seems to work fine. I don't have anything to compare it to to measure its accuracy. But it was easy to use and it is a good workable size. May 21, 2013
