T-Micro CO 2 Controller


The T-Micro CO 2 Controller is the smallest CO 2 controller from TechGrow. This simple variant is by far the best in its category due to the full digital technology. You can use the T-Micro CO 2 Controller in any room. Thanks to the external CO 2 sensor with light sensor, it switches automatically between day and night settings. It is adjustable from 300 to 2000 ppm and takes a measurement every second. The display shows the current values, including setpoint and hysteresis. The controller automatically switches the CO 2 source on and off, and the indicator LED shows when CO 2 is being dosed. Because the T-Micro CO 2 Controller has a built-in calibration function, you can calibrate the CO 2 sensor in the open air.


The T-Micro CO 2 Controller is supplied without sensor.




  • Plug & Play.
