External, active CO2 sensor with its own alarm, LEDs and test button, for connection to the warning devices GX-A1+ or GX-HS, detects CO2 from used air or CO2 exhaled by people, as a timely reminder to ventilate at about half the MAC (2500 ppm).
Performance features
External sensor for the gas detectors GX-A1 and GX-HS
Mains operation also possible without warning device
Detection of carbon dioxide (CO2): Reminder to ventilate regularly
DESCRIPTION
The GX-CO2-25 gas sensor is a sensor for measuring carbon dioxide (CO2) for monitoring indoor air quality in homes, offices, stores and training rooms - rooms where people regularly spend time. Concentration limits and alarm thresholds are based on the recommendations of health and environmental authorities. The threshold value for the pre-alarm is approx. 2000 ppm and for the main alarm 2500 ppm, half the MAK (max. workplace concentration).
Can be connected as an accessory to our gas detectors GX-A1 (300892) or GX-HS (400200) or as a gas detector for stand-alone operation with plug-in power supply 5V / min. 300mA, with LED indicators for operation, fault, alarm directly on the sensor, as well as integrated test button for manual alarm triggering. Concentration limits and alarm thresholds are based on the recommendations of health and environmental authorities.
