CO2 controllers

The T-1 Pro CO2 controller is the most advanced CO2 controller on the market. It creates exactly the CO2 level you want in your grow room. Set up the T-1 Pro in one minute and enjoy all its features! For example, the T-1 Pro has an automatic CO2 dosing counter, a log of the last 7 days and adjustable pulse dosing to keep the CO2 level in your room stable. It also has a dosing delay, which ensures delayed activation of CO2 enrichment in your room.The T-1 Pro can be set from 300 to 2000 ppm or from 300 to 10000 ppm. The clear display shows the current values of the connected sensors as well as the minimum/maximum values. The T-1 Pro controller switches automatically between day and night settings using light detection. Thanks to the integrated calibration function, you can calibrate your CO2 sensor in outdoor air.The T-1 Pro is supplied without a sensor.   Product features:  Adjustable from 300 to 2,000 ppm or from 300 to 10,000 ppm. Adjustable dosing delay and timer. Automatic CO2 dosing counter Dosing log of the CO2 counter over a period of 7 days. Pulse dosing function for metered addition of CO2. Built-in calibration function for calibrating the CO2 sensor in outdoor air. Depending on the connected sensors, CO2, temperature and humidity values are displayed. The display shows the minimum/maximum values of the connected sensors. The display is updated every second. LED indicators for CO2 dosing, light detection and a stable climate. Compatible with several TechGrow devices. All settings are saved in the event of a power cut. The controller switches automatically between day/night mode (via the connected sensor). Switches the display backlight off automatically after 60 seconds. Automatic detection of a broken cable or poor connection to the sensors. UTP connection. Sensor not included. The sensors are available separately (0-2,000 ppm / 0-10,000 ppm). Option to connect the TechGrow data logger (DL-1).  

The T-2 Pro CO2 controller is the extended version of the T-1 Pro CO2 controller. The additional built-in climate controller lets you control the CO2 level as well as the temperature and humidity in your room. This unique combination lets you dose CO2 during the day and extract excess CO2 and moisture produced by your plants at night. The TechGrow T-2 Pro CO2 controller also keeps the temperature in your room at the desired level. The measuring range of this CO2 controller is 300 to 2000 ppm or 300 to 10000 ppm, selectable by the user. The connected sensor allows automatic switching between day and night mode.The T-2 Pro CO2 controller is a fully equipped device with built-in dosing delay, timer, dosing counter and memory for display data such as the minimum and maximum CO2 level. This CO2 controller also has a unique calibration function for perfectly matching your fan. Special hardware and software make the fan control run smoothly and silently.The T-2 Pro CO2 controller has a robust, splash-proof housing and is easy to operate with a push-and-turn knob. The information is easy to read on the bright, large LCD display.Note:The T-2 Pro CO2 controller is supplied without a sensor.Recommended sensor: S-4 sensor / 0-2000 ppm. Versions: 4.5 A - 7 A and 14 A   Product features: Measures and regulates CO2, temperature and relative humidity at the same time, day and night. Extracts excess CO2 from the air at night. Shows the minimum/maximum values of the connected sensor. Adjustable from 300 to 2,000 ppm or from 300 to 10,000 ppm. Adjustable dosing delay and timer. Automatic CO2 dosing counter. Dosing log of the CO2 counter for the last 7 days and display of the total (cumulative) dosing time. Pulse dosing for metered addition of CO2. Built-in calibration function for CO2 and temperature. The display is updated every second. Indicator LEDs for CO2 dosing, light detection and a stable climate. All set, hysteresis and alarm values of the sensor can be set individually. Quick menus for a handy overview of all settings. Suitable for connecting fans up to 5,000 m3/hour (7 A) and up to 10,000 m3/hour (14 A). The fan control has 2 settings: automatic or manual. Fan and CO2 relays are fused separately. All settings are saved in the event of a power cut. The controller switches automatically between day and night mode via the light sensor. UTP connection. Various sensors are available separately (0-2,000 ppm/0-10,000 ppm). Option to connect the TechGrow data logger (DL-1).

The T-Micro CO2 controller is the smallest CO2 controller in the TechGrow range. Thanks to its fully digital technology, this device is by far the best in its class.You can use the T-Micro CO2 controller in any room. It switches the CO2 source on and off automatically. You can use the T-Micro CO2 controller in any room. It switches the CO2 source on and off automatically. The external CO2 sensor with light sensor switches automatically between day and night settings.The T-Micro CO2 controller can be set from 300 to 2000 ppm and takes a measurement every second. The display shows the current values, including set point and hysteresis, and the indicator LED shows whether CO2 is being dosed or not. The T-Micro CO2 controller also has a built-in calibration function, so you can calibrate the CO2 sensor in outdoor air.This CO2 controller is supplied without a sensor.   Product features:  Plug & play. Can be used in small to very large rooms. Built-in calibration function for calibrating the CO2 sensor in outdoor air. Adjustable from 300 - 2000 ppm. Min/max display for CO2. The indicator LED shows when CO2 is being dosed. Switches the CO2 source (CO2 generator, CO2 cylinder) on/off via a 230 V relay. Memory for set point and hysteresis in case of a power cut. Automatic 110 V/230 V detection. The external sensor has a light sensor that switches automatically between day and night settings. Automatic detection of a broken cable or poor connection to the sensor(s). Sensor connection with a standard network cable (UTP). A 5-metre cable is included. Controller and sensor are available separately. Various sensors are available separately. Option to connect the TechGrow data logger (DL-1).

The T-Mini from the TechGrow Pro series is a very complete and compact all-in-one CO2 controller that is easy to operate with just one button. The display shows the current CO2, temperature and relative humidity values at a glance. The T-Mini also records the minimum and maximum values for CO2, temperature and humidity and controls CO2 dosing for an optimal CO2 concentration in your room. The built-in fan guarantees optimal airflow and therefore fast and accurate measurement.The T-Mini is fitted with an internal non-dispersive infrared sensor (NDIR) and a light sensor (LDR). The light sensor switches automatically between day and night mode, so no CO2 is dosed in night mode. You can switch the light sensor off to allow 24/7 dosing, so the T-Mini continuously maintains the desired CO2 level. Product features: Adjustable from 300 to 2000 ppm. Built-in CO2, temperature and humidity sensor. Built-in light-dependent resistor (LDR)/light sensor. Shows the current value and the minimum/maximum values for CO2, temperature and humidity. The display updates every second. Built-in calibration function for calibrating the CO2 sensor in outdoor air or indoors. Built-in fan for optimal airflow. This ensures accurate and fast measurement. Indicator LEDs for CO2 dosing and a stable climate. Memory for set point and hysteresis in case of a power cut. Thanks to the built-in light sensor, the controller switches automatically between day and night mode. Display backlight switches off automatically after 60 seconds.
