  1. Just a warning to everyone in case you didnt know, the CO2 monitors that rely on Infrared (such as the ppm-3) are susceptible to RF interference caused by electronic ballasts and similar devices... and will read wrong / freeze up if these things are too close.
    This was mentioned by tech support @ C.A.P. while diagnosing a monitor problem.
