Our company supplies hydrogen sulfide alarm which can continuously detect the concentration of hydrogen sulfide in the environment. Hydrogen sulfide alarm is controlled by microprocessor with powerful functions. With large-scale digital integrated circuits and micro-power components, the signal of gas concentration in air is converted into electrical signal, which is displayed directly by LCD screen. When the measured gas concentration in the environment reaches or exceeds the preset alarm value, the alarm immediately sends out acoustooptic alarm. At the same time, LCD displays the current concentration value, and the performance of the whole machine is in the leading level in China. Hydrogen sulfide alarm is suitable for detecting the concentration of poisonous gases in ambient air. Hydrogen sulfide alarm = (gas alarm controller)+ (multiple gas detectors) constitute an alarm system (as shown in the figure), which can monitor and centralize multiple gas leakage points. Installation of network is convenient, sound and light alarm to remind users to take safety measures, and drive exhaust air, cut off, spray system is widely used in metallurgy, power plants, chemical industry, mines, tunnels, tunnels, underground pipelines and other places, effectively prevent the occurrence of poisoning accidents.
