The smallest controller in our series. A complete and very easy to operate CO2 controller. Best in its class thanks to its completely digital technique.

The TechGrow T-Micro CO2 Controller is a digitally controlled device that measures and regulates the CO2 value in a room. Automatically switches between Day/Night settings by means of the external CO2-sensor and light sensor.

The T-Micro CO2 Controller has a robust casing and is equipped with an LCD-display.

Furthermore, the T-Micro’s built-in calibration function makes it possible to calibrate the CO2 sensor against outdoor air.

Special features:

• Plug & Play, can be used in small to very large rooms.
• Extremely accurate external CO2 sensor, produced by SenseAir® Sweden, the leading manufacturer in CO2 measurement.
• Built-in calibration function to calibrate the CO2 sensor against outdoor air.
• Adjustable between 300 – 2000 ppm.
• The sensor takes a measurement every second.
• Turns the CO2 source (CO2 generator, CO2 cylinder) on/off using a 230V relay.
• Memory in case of power outages for setpoint and hysteresis.
• Automatic 110V – 230V detection.
• LED indicates when CO2 is being dosed.
• The external CO2 sensor has a built-in light sensor to automatically switch between Day/Night settings.
• Automatically detects broken cable or bad connection of the connected sensors.
• Connecting the sensor is done with a standard (UTP) network cable. Included is a 5 meter cable.
• Controller and sensor are available separately.
• Possibility to connect the TechGrow AM-T: a SMS-module to remotely monitor the CO2 concentration.
