The hydrogen sulfide gas alarm is used to monitor the concentration of hydrogen sulfide gas in the ambient air. Its standard measurement range is 0-20 / 50 / 100ppm and it has the function of sound and light alarm. When the hydrogen sulfide in the work place reaches the lower limit of the alarm value At this time, the hydrogen sulfide alarm will start to alarm. At this time, workers can take necessary protective measures to protect themselves from the danger of hydrogen sulfide gas. Therefore, install hydrogen sulfide gas detection in factories, mines and other workplaces that may cause hydrogen sulfide poisoning. The alarm is very necessary, which can not only improve the efficiency of safety production, but also directly and effectively prevent hydrogen sulfide poisoning accidents.
Many people think that as long as there is a leak of hydrogen sulfide gas near the gas alarm, the alarm will give an alarm signal. Without alarm, the alarm may malfunction. This understanding is wrong. The detection object of the alarm is sulfur in the air. Hydrogen gas, the detection range is: 0-100ppm, only when the concentration of hydrogen sulfide gas reaches the set value, the hydrogen sulfide gas alarm will give an alarm, not the presence of hydrogen sulfide gas will give an alarm.
