The CO2-2 is fused and rated at 10-amps.The CO2-2 has 2-timers which control the CO2 injection duration time, (30 seconds to 20 minutes) and the frequency of the injection cycles (3 to 120 minutes). Built in photocell ensures CO2 only operates during the Day. Plug our PPM-1a in for CO2 parts per million accuracy.
