With the continuous improvement of coal mine safety and the widespread application of gas monitoring system, the detection means of harmful gases are becoming more and more perfect. The large and medium-sized mines have formed a detection system combining manual fixed-point, timing detection and automatic monitoring. Among the manual detection methods, in addition to the sampling analysis method, the use of a portable gas detector is currently the most widely used or rapid assay.

yiyuntian technicians recommend the following suitable portable gas detectors, namely: portable two-in-one gas detector MS600-2(CO, H2S) and handheld helium detector MS500-He And hand-held methane gas detector MS500-CH4.

By configuring the corresponding sensors and alarms, and transmitting the monitoring signals to the monitoring center through communication, the data is analyzed through the supporting integrated management software.Through the software, the geographical location, measured value or working state of each measuring point are continuously collected. In case of abnormality, the system will automatically generate alarms (sound and light alarm, short message alarm, etc.) to inform relevant personnel at the first time, so as to eliminate possible dangerous situations in the bud and avoid causing large economic losses and affecting the normal operation of pipes and culverts.

Yiyuntian has a high-performance fixed gas detection and alarm equipment independently developed according to the gas generation characteristics of the industry, which can realize 24-hour all-weather monitoring. For work area operation, portable gas detector is a necessary instrument for personal protection and safety.
