Pro Leaf PPM-1 Digital CO2 Controller

High-precision and easy-to-use digital CO2 controller. Accurately measures and controls the carbon dioxide level in the grow room, precisely maintaining the desired carbon dioxide PPM level. Its large, easy-to-read LCD screen shows exact PPM readings down to a 1 PPM resolution. It can be configured to operate in Fuzzy Logic mode with tank and regulator systems to improve CO2 distribution efficiency. When used in Fuzzy Logic mode, the built-in microprocessor applies calculations to the injection program specifically to help eliminate CO2 if required. The default standard "logic" mode is designed for use with a CO2 generator (propane gas). This controller's smart and sensitive remote combination probe features a high-precision NDIR CO2 sensor with a built-in photocell for day/night detection. It also comes equipped with rubber feet on the back of the unit for added protection when mounted, apart from optional "U" brackets for tent mounting. It mounts equally well in greenhouses and grow cabinets, including two mounting kits with each controller.
