AirTECH agro+/V10

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.

Features

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
