CO2 Gas Detection Calibration Technologies

The typical CO2 Gas Sensor for refrigerant leak detection should be ranged 03% CO2, with warning set points at % (8 Hour TWA allowable exposure) and alarm set points at % (10,000ppm) CO2. With the above warning and alarm setpoints, the recommended actions would be to investigate a potential Carbon Dioxide leak at %, and shut down valves to the evaporator and evacuate the room at %.
