TechGrow T-1 Pro CO2 Controller/Regulator/Monitor

The TechGrow T-1 Pro CO2 Controller is the most advanced carbon dioxide regulator on the market. It precisely maintains the desired CO2 levels in your grow room, making it one of the most effective CO2 regulators available. Easy to configure yet packed with professional features, it’s perfect for beginners and experienced growers alike.

Its automatic CO2 dosing counter, adjustable pulse dosing, and dosing delay function allow you to maintain stable CO2 levels and ensure your grow stays optimal even when you're not around. The automatic logging function records dosing data for 7 days, while the display shows real-time readings, including min/max values.

Adjustable from 300 to 2000 ppm or 300 to 10,000 ppm (with optional sensor). The controller automatically switches between day and night modes via light detection and includes a built-in calibration function for the CO2 sensor in fresh air.

The T-1 Pro is sold without a sensor. It is compatible with TechGrow’s range of CO2 sensors.
