Product model withdrawn from sale

Device group: Ventilation controllers
Device type: AirTECH agro+

AirTECH agro+ is an ventilation controller used to monitor indoor carbon dioxide concentration in the range of 0÷5000 ppm (optionally up to 20% v/v). Measurement of CO2 is realized by state-of-the-art non-dispersive infrared sensor.

In particular, the unit is designed to be used in greenhouses, mushroom farming, food transportation etc.

AirTECH agro+ is supplied with a control module with relay outputs to control the ventilation system and 12VDC alarm outputs for signaling. Optionally the module can be equipped with 4-20mA output and/or RS485 MODBUS digital output.


AirTECH agro+ consists of two units: a remote CO2 sensor (to be mounted in the monitored room) and a control module.

CO2 sensor
  • state-of-the-art non-dispersive infrared (NDIR) technology to measure carbon dioxide gas concentration;
  • 4-20mA analog output;
  • internal automatic self diagnostic and calibration;
  • long sensor operating lifetime (> 10 years);
  • wall-mounted housing (IP43) with standard connecting cable (10m, can be upgraded up to 150m);
  • universal mounting bracket;
  • all sensors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No AP150).
Control module
  • internal digital control unit type MDP1.A/T, with 3 threshold levels (settable from push-buttons), 4-digit LED display, 7 status LEDs;
  • IP54 wall-mount cabinet;
  • Standard 4 relay outputs (max 250VAC);
  • 12VDC power supply + 230VAC power-on switch mounted on standard 35mm rail;
  • Optionally: 4-20mA analog output and/or RS485 MODBUS digital output.
