T-Micro MKII CO2 Controller by TechGrow

T-Micro MKII CO2 Controller

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.

Special features:

  • Plug & Play, can be used in small to very large rooms.
