Portable CO2 Detector and Alarm

My short term review is 5 stars

It works It works well. Fast to respond when testing easy to see numbers. It has accurate co2 It has accurate temp It has accurate Humidity. The battery Life is good. The only thing left is long term life of the meter. Since I have it for 17 days I can not comment on that Maybe I follow up in six months and a year.

Helpful CO2 Meter

The CO2 meeter we received is filling our need to help us determine the air exchange in our home and office. It unfortunately only has a 24 hour battery but otherwise seems to be doing what's needed.

CO2 meters

I've purchased 3 type of CO2 meters from your company and one O2 meter. The simple CO2 meters are wonderful, the O2 meter has a bad charging receptacle and the most recent hand held CO2 meter is difficult to use
