TechGrow T-Micro CO2 Controller

The TechGrow T-Micro CO2 Controller is the smallest CO2 controller in the TechGrow range, yet the best in its category thanks to its fully digital technology.

Suitable for any space, the T-Micro automatically controls the CO2 source, turning it on and off based on the setpoint. The external CO2 sensor (not included) features a built-in light sensor for automatic day/night switching.

The controller is adjustable from 300 to 2000 ppm, measures CO2 concentration every second, and displays current values, setpoint, and hysteresis on the screen. The status LED indicates when CO2 dosing is active. It also features a manual calibration function for the CO2 sensor in fresh air.
