TECHGROW T-Mini Pro CO2 Controller/Regulator/Monitor

From our Pro Series, the T-Mini is the most powerful compact all-in-one CO2 meter and controller on the market. Made simple to operate by design it has just one knob and is ideal for those trying their hand at hydroponics/aquaponics, those putting together an indoor grow kit or greenhouse kit for the first time as well as the more seasoned urban gardener looking to upgrade their kit!

The vivid display on the T-Mini acts as a CO2 monitor, readily displaying the current carbon dioxide concentration, temperature as well as relative humidity, with all values updated every second. Minimum and maximum values of CO2, temperature and air humidity are all registered and CO2 dosage is automatically controlled to maintain an optimal CO2 concentration in your grow room for the biggest buds or plumpest veg you have ever grown. With its built-in fan, optimal air flow and therefore prompt and precise measurements are guaranteed.

Able to automatically switch between day and night modes thanks to its built-in light sensor, with no CO2 being dosed during the night. However, you have the option to switch off the light sensor to enable 24/7 dosing and continuously maintain your desired CO2 levels. The carbon dioxide sensor is a non-dispersive infrared sensor (ndir), which provides precise measurements, and also helps ensure your desired CO2 concentration at all times.
