OPERATING INSTRUCTIONS FOR LEEC AUTOMATIC CO2 …

An Infrared (IR) CO2 sensor is used to detect the CO2 levels. If the CO2 level is below the required set point, the control system opens a solenoid valve to inject CO2 gas into the chamber to bring the chamber atmosphere back to the set level. When the door has been opened, twostage recovery of the CO2 level starts. This is achieved by controlling both coarse and fine flow of CO2 into the ...

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 %.

CO2 Sensor Calibration: What You Need to Know |

Most of our CO2 products use nondispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 molecule counts.
