Chemical Hazardous Gas Detector

Chemical hazardous gas detectors identify changes in gas molecule concentrations through sensors, converting chemical signals into electrical signals to display numerical values. They are used in factories and laboratories to monitor leaks and ensure personnel safety.
Selection
Select the appropriate sensor based on the type of gas to be measured, ensuring that the measurement range and accuracy meet the environmental requirements. Verify the explosion-proof rating and protection standards, and check whether the data logging and alarm functions are suitable for the site.
