TECHGROW T-1 PRO CO₂ Controller

The TECHGROW T-1 PRO is a precise and user-friendly CO₂ controller designed to reliably regulate CO₂ levels in your grow room. Its simple setup allows you to get started quickly, while its intelligent features ensure controlled and consistent CO₂ delivery.

Key features include an automatic CO₂ dosing counter, a seven-day dosing history and adjustable pulse dosing. The integrated dosing delay allows you to control exactly when CO₂ enrichment begins.

Depending on the sensor used, the measuring range can be set to 300–2,000 ppm or 300–10,000 ppm. The clear display shows current readings as well as the minimum and maximum values of connected sensors. The display updates every second.

Using the connected light sensor, the T-1 PRO automatically switches between day and night mode. Its integrated calibration function allows the CO₂ sensor to be calibrated in fresh air.
