How to use the gas detector correctly and what should be paid attention to before use
For the chemical industry, gas industry, metallurgical industry and other industries, gas detection is one of the very important safety procedures, because there are irritating gases and asphyxiating gases in the industrial production process, these gases are mostly corrosive, and pass through the respiratory tract Entering the human body can cause acute poisoning. Therefore, gas detectors have been widely used in various industries.
Before using the gas detector:
① Carefully read the instruction manual corresponding to the gas detector before operation, and be familiar with the performance and operation method of the machine.
② Check whether the battery power is sufficient. If the battery power is found to be low, replace the battery in time.
③ Check whether the air filter at the air inlet is blocked by debris, and the blockage needs to be cleaned or replaced.
④ Press and hold the start button for three seconds to enter the self-inspection state when starting up, and observe whether the low alarm value and high alarm value set by the detector are accurate (the first-level alarm for CO detector is 50ppm, the second-level alarm is 100ppm; the first-level alarm for oxygen detector is 100ppm; Level 1 alarm 19.5%, level 2 alarm 22%; hydrogen sulfide detector level 1 alarm 10 ppm, level 2 alarm 15ppm), if it does not meet the requirements, the settings are not allowed to be used, and should be corrected immediately.
⑤ During self-inspection during start-up, you should listen to whether the graded alarm, sound and light alarm, and vibration alarm are accurate. If the setting does not meet the requirements, it is not allowed to use, and it should be corrected immediately.
⑥Observe whether the initial value is accurate after turning on the machine under fresh air conditions (the initial display of CO detector is 0 ppm; the initial display of O2 detector is 20.9%; the initial display of hydrogen sulfide detector is 0 ppm). revision.
