TechGrow T-2 Pro CO2 Controller/Regulator/Monitor (14A)

The TechGrow T-2 Pro CO2 Controller is the advanced version of the T-1 Pro, offering the most complete CO2, temperature, and humidity control available. It’s the ultimate all-in-one solution for hydroponics setups, urban farms, and greenhouses, combining CO2 regulation, fan control, and climate management in a single device.

With its advanced functions, the T-2 Pro allows you to dose CO2 during the day, extract excess CO2 and moisture at night, and regulate temperature for a perfect environment 24/7. The smooth fan control ensures quiet operation, improving safety and comfort in your workspace.

Features include pulse dosing, dosing delay, timer, automatic CO2 counter, 7-day data log, and manual calibration for CO2 and temperature. The T-2 Pro is compatible with TechGrow CO2 sensors (sold separately, S-4 2000 ppm recommended) and stores all settings during power failures.
