The T-Micro CO² Controller is the smallest CO² controller from the TechGrow range. This device is by far the best in its category, due to the complete digital technique.

You can use the T-Micro CO² Controller in any room. It automatically turns the CO² source on and off. The external CO² sensor with light sensor enables automatic switching between day and night settings.

The T-Micro CO² Controller is adjustable from 300 to 2000 ppm and performs a measurement every second. Its display shows actual values, including setpoint and hysteresis, and the indicator LED indicates whether CO² is being dosed or not. Moreover, the T-Micro CO² Controller has a built-in calibration function, so you can calibrate the CO² sensor in fresh air.

This CO² controller comes without a sensor.
