Objectively speaking,gas detectorThe reason why it cannot be used or damaged is because the quality factor is only part of the selection of ordinary manufacturers, and most of it is caused by improper selection and use. Belowgas detectorThe editor has listed the options for gas detector for you. Be aware of common mistakes in use.
Acceptance error: High concentration gas detection case: customer on-site installationFlammable gas detectorsAfter that, use a lighter to check whether the detector is working normally. After the ventilation test, the detector alarms, but it cannot be reset to zero. After normal use and detection of sensor damage, all sensors will be returned to the factory for replacement.
Analysis: Many customers prefer to use high-concentration gas for inspection during acceptance. This method is imprecise and can easily damage the instrument.Combustible gas detectorThe detection range is 0~100%LEL, the lower explosion limit is low (methane is 0~5%vol), and the lighter gas is high-purity butane, which is far beyond the detection range. Range of Combustible Gas Detector:
When testing with lighter gases, the sensor is subjected to 2 to 3 or more shocks, and the chemical activity of the sensor element decays or stops prematurely, resulting in reduced accuracy and sensitivity. The platinum wire burned out and the sensor was scrapped. It is important to note that the manufacturer cannot guarantee that sensor failures caused by the impact of highly concentrated gases will need to be replaced at their own expense.
Analysis: Most on the marketFlammable gas detectorsAdopts the principle of catalytic combustion. The principle of catalytic combustion is to use catalytic energy to generate low-temperature flameless combustion on the catalytic element, and the combustion heat raises the temperature of the element.
