TechGrow T-2 Pro CO2 Controller/Regulator/Monitor (7A)

The TechGrow T-2 Pro CO2 Controller is the extended version of the T-1 Pro, designed to regulate CO2, temperature, and humidity in a single device. With its built-in climate control function, you can dose CO2 during the day, remove excess CO2 and moisture at night, and maintain optimal temperature 24/7. Ideal for greenhouses, grow rooms, and hydroponics setups, it’s a robust, reliable, and user-friendly all-in-one system.

The T-2 Pro (7A) supports fans up to 5000 m³/h and offers advanced features such as pulse dosing, dosing delay, timer, automatic CO2 counter, 7-day CO2 log, and min/max value display. The controller automatically switches between day and night using the light sensor (not included) and allows calibration for CO2 and temperature sensors.

Note: The T-2 Pro comes without a sensor. Recommended sensor: S-4 (0–2000 ppm).
