Ive had one in my house for 9 years. Bought one like mine for my mother in law’s rental house. It must be a new law.
Excellent unit. Received it fast. This is the second unit we've purchased from CO2 meter. Answered all my questions when I phoned and asked about it. We will buy from them again.
I have not managed to mount it in the submarine yet. Will it work as I want, then this will be great.
I had a hard time ordering it just because there is a lot of credit card fraud. The company was thorough once all the financial stuff was taken care of I had my monitor in two days. It's the second one that I have because of its ease-of-use and the price is right as well :-)
We have installed two of the meters in our production area...Our CO2 tank gassed off yesterday and the meter near it worked perfectly.
