GLH100 Mining Hydrogen Sulfide SensorDetailed product description：

The GLH100 mining hydrogen sulfide sensor is used for continuous detection of hydrogen sulfide content in the air of coal mines or non coal mines, and has real-time on-site display of content values, over limit sound and light alarms, and other functions. It can be used alone or in conjunction with various mining safety monitoring systems. This sensor adopts imported original sensing components, with stable operation, long service life, LED digital display, intrinsic safety circuit, intelligent chip control, infrared remote control calibration, and multiple signal output formats. Especially suitable for continuous monitoring of hydrogen sulfide concentration in high sulfur mine environments.

Environmental requirements for the use of GLH100 mining hydrogen sulfide sensor
The environmental conditions required for the sensor to function properly are:
a) Environmental temperature: 0 ℃ to+40 ℃;
b) Humidity: ≤ 98% RH;
c) Atmospheric pressure: 80 kPa to 110 kPa;
d) In situations where there is no significant vibration, impact, or water splashing;
e) Wind speed: (0-8) m/s;
f) There is an explosive gas mixture of methane in coal mines, but there is no corrosive gas that can damage insulation.
