Customer Questions & Answers

How accurate is this meter?

Asked by: Daniel
It seems accurate for the amateur to identify further needs, which we figured should be drawing the attention of the professional. It will have limited use for what we have planned as well. Heavy use and particular problems may dictate the need for a heavier investment. This was reasonably priced and is valued even more highly by meeting our own expectations.

For this, it worked very well. I would also add that it arrived at the store well ahead of when was anticipated with the Holiday Season. It was simple enough for amateurs, which we were, and yet gave the professional results we desired. I was not sure of how much control we had of the alarm, which may have given an uncomfortable feeling that was not desired for our use but may have been just what an inspector might need. Overall it was great and came well-recommended. It is now once more recommended for value and effectiveness; this time by us.

Rated 3 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 2 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from Has all of the features I need Very easy to set up. Instructions are well written. I tested it on several known values and was quite surprised to fin d out how accurate this product performed. It exceeded my expections.

Rated 4 out of 5 by from This product is a great value. These do no last as long as the more expensive models, because they cannot be re-calibrated. But they are so much less expensive that over a 10 year period they are a much better value.

Rated 3 out of 5 by from The product did not meet my needs I need a monitor that will stay on for as long as I need it on a job, at least a couple hours. This one has an auto shutoff that shuts it down after 15 minutes, and does not save the values. A manufacturer's engineer confirmed it cannot be overridden.
