Digital CO2 PPM controller, for Regulator & Generator

Standalone CO2 PPM Controller for Regulators and Generators

This TrolMaster controller pairs a precision NDIR CO2 sensor with a built-in photocell to automatically activate supplemental CO2 only during daylight hours.

Adjustable deadband, min-max recall, and a fuzzy logic feature help it more accurately control compressed CO2 systems.

The remote sensor connects with a 16 ft cable for placement close to the plant canopy, and can be re-calibrated for years of accurate operation.
