Very affordable, and simply all you need to regulate CO₂. This CO₂ controller can accurately monitor room CO₂ levels and turn CO₂ regulators or generators on and off. The monitor is preprogrammed to turn devices on at 1300 ppm and off at 1500 ppm with overshoot already calculated. Instead of a costly digital readout, the HydroGEN CO₂ monitor uses indicator lights to show approximate CO₂ levels. Hydro Innovations uses a high quality, self calibrated, maintenance free SenseAir brand Infrared CO₂ detector. The monitor has a standard 120V piggyback plug and includes an easy mounting wall bracket.
