6 Common Misconceptions About Gas Detectors
Gas detector is one of the detection instruments commonly used in industrial production. It can detect the concentration of toxic and harmful substances at work, detect the types of gases in the environment, and use corresponding safety protection equipment based on the detection results. However, when using gas detectors, people sometimes have some misunderstandings. Details are as follows:
Myth 1: Gas detectors can detect any gas
A detector can only detect one specific gas. Composite gas detectors can only detect several gases at the same time.
Myth 2: Gas detectors can be installed at will
Strictly require the installation location of gas detectors. The installation position is incorrect and cannot be detected normally.
Misunderstanding 3: Use high concentration gas test during acceptance
Some customers use high concentration gas for testing during the acceptance process. This approach is very loose and can easily damage the instrument. The detection range of the combustible gas detector is 0~100% LEL. Testing with gases with a concentration higher than this range may fumigate the sensor, causing damage to the sensor or detection failure!
Myth 4: As long as there is flammable or toxic gas around the gas detector, the alarm should sound an alarm
The condition for the gas detection alarm to alarm is that an alarm signal will be issued only when the measured gas concentration reaches or exceeds the preset value of the instrument.
Myth 5: Damage to the explosion-proof facilities of the gas detector does not affect its use
During use, if the alarm explosion-proof seal is damaged or loose, the explosion-proof pipe ruptures, or other explosion-proof facilities are damaged, it must be repaired in time.
Myth 6: Gas detectors do not require maintenance and upkeep
A gas detector is a measuring instrument that requires regular calibration to ensure the accuracy of its detection. Gas detectors used for a long time will drift. If not calibrated in time, the error will become larger and larger, causing safety hazards.
