TECHGROW T-2 PRO CO₂ Controller

The TECHGROW T-2 PRO is an advanced CO₂ controller with an integrated climate control system. It monitors and regulates CO₂ levels, temperature and relative humidity in your grow room. Its automatic day and night mode helps maintain an optimal climate throughout the entire plant cycle.

During the day, the T-2 PRO controls the CO₂ supply. At night, excess CO₂ and moisture released by the plants can be extracted through the connected ventilation system. The controller also maintains the room temperature at the desired level.

Depending on the sensor used, the measuring range can be set to either 300–2,000 ppm or 300–10,000 ppm. An external light sensor automatically switches the controller between day and night mode.

Intelligent Control and Advanced Features

The T-2 PRO offers a wide range of useful features, including dosing delay, timer, automatic CO₂ dosing counter and data memory. It records minimum and maximum readings as well as CO₂ dosing times for the previous seven days.

The integrated calibration function allows precise adjustment of the fan control. Its dedicated control technology ensures smooth and quiet operation. The robust, splash-resistant housing, intuitive rotary control and large LCD display make the T-2 PRO easy and convenient to use.
