Several misunderstandings about the use of gas detectors
The gas detector is one of the detection instruments commonly used in industrial production. It can detect the concentration of toxic and harmful substances in our work. The gas detector can detect the types of gases existing in the environment, and use corresponding safety protection according to the detection results. supplies. However, in the process of using the gas detector, some misunderstandings are sometimes encountered. details as follows:
Myth 1: A gas detector can detect any gas
A detector can only detect one specific gas, and a compound gas detector can only detect several types of gases at the same time.
Myth 2: The gas detector can be installed at will
There are strict requirements on the installation position of the gas detector. If the installation position is not correct, there is no way to detect it normally.
Misunderstanding 3: Test with high concentration gas during acceptance
Some customers used high-concentration gas for testing during acceptance, which is very imprecise and likely to cause damage to the instrument. The detection range of the combustible gas detector is 0~100%LEL. We use a gas with a concentration higher than this range for testing. It is very likely that the sensor will be smoked, causing sensor damage or detection failure!
Misunderstanding 4: As long as there is flammable gas or toxic gas around the gas detector, the alarm should sound an alarm
The condition for the gas detection alarm to alarm is that the gas concentration to be measured reaches or exceeds the preset value of the instrument before it sends out an alarm signal, and it does not mean that the alarm will be triggered when there is gas.
Misunderstanding 5: Damage to the explosion-proof facilities of the gas detector itself does not affect the use
During use, sometimes the explosion-proof seals of the alarm are damaged, loose, and the explosion-proof pipes are broken and other explosion-proof facilities are damaged and no one cares about them.
When these problems occur in the gas detection equipment, timely maintenance and repairs are required.
