        Very good device

        We use this device to monitor CO2 and Ammonia levels on our chicken farms. It is very handy and accurate. So much so that we are now thinking of getting a model that also includes carbon monoxyde and have it become standard equipment for our representatives and farm managers.

        "Easy to install, easy to set up, and easy calibration - just what I was looking for."
