CO2 Gas Detection - Calibration Technologies

CO2 Gas Detection-Refrigerant Leak Detection. When CO2 is used as refrigerant in a cascade system. Choosing Alarm set points and actions for CO2:. The typical CO2 Gas Sensor for refrigerant leak detection should be ranged 0-3% CO2, with warning set points at 0.5% (8 Hour TWA allowable exposure) and alarm set points at 1.0% (10,000ppm) CO2.. With the above warning and alarm set-points, the ...

CO2 Sensors Products | CO2Meter.com

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 0-1% (0-10,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.

Carbon dioxide - CDC

Other human data: Signs of intoxication have been produced by a 30-minute exposure at 50,000 ppm [Aero 1953], and a few minutes exposure at 70,000 to 100,000 ppm produces unconsciousness [Flury and Zernik 1931]. It has been reported that submarine personnel exposed continuously at 30,000 ppm were only slightly affected, provided the oxygen content of the air was maintained at normal ...
