The T-2 Pro (7A) is the extended version of our T-1 Pro, building on what is already the most advanced of its kind on the market. It comes with an additional built-in climate control function, allowing you to control CO² levels of your grow room as well as the temperature and humidity. This makes it an all-in-one solution for your hydroponics set up, urban farm or greenhouse, acting as a carbon dioxide sensor, as well as fan controller for temperature regulation and humidity.

With this unique combination of functions, The T-2 is truly a smart sensor with which you can do more than ever before. CO² can be dosed as per your requirements during the day, and any excess CO² or moisture produced by your plants throughout the night can be sucked in. Together with its temperature regulation function, you can ensure that your plants are in their ideal environment round the clock – helping you grow the big buds or plump veg you’ve always wanted.

A feature-packed device for your existing indoor grow, or as part of a new grow kit or greenhouse kit, the T-2 provides the ultimate in convenience. The fan control is able to operate smoothly, giving you a noiseless fan and massively increasing workplace health and safety, as well as comfort levels. To help you regulate CO² levels with ease, it comes with a built-in dosing delay, timer and dose counter. With its built-in memory, its able to store performing display data such as maximum and minimum CO² levels from the CO² meter.

The T-2 Pro is housed in a robust, splash-proof body, making it the most reliable environmental control device for your room. Its single push-and-turn knob allow you to easily control operation and the large, bright LCD screen displays informational clearly for you to read.

The T-2 Pro comes without sensor. It is compatible with our range of Techgrow carbon dioxide sensors, which act as CO² monitors and are designed specifically for our CO² regulators. We recommend you use the S-4 CO² Sensor (2000ppm)
