This digital CO2 PPM Controller is a high performance product. Connect to CO2 generator or canister, dial in the required PPM of CO2 and the digital CO2 controller will detect PPM of CO2 and activate/deactivate the release devise to maintain settings.
The controller includes a highly accurate NDIR CO2 sensor that is located in a remote sensor enclosure and can be positioned several metres from the main controller. Used with a timer, you can ensure CO2 release only occurs during lighting hours.
