GTH1000(B) Type Mining Carbon Monoxide SensorDetailed product description：

The GTH1000 (B) type mining carbon monoxide sensor is suitable for continuous measurement of carbon monoxide concentration in environments with carbon monoxide gas such as underground mining faces, return air tunnels, and mechanical and electrical chambers in coal mines. It can not only be used in conjunction with KJ379-F mining substation and KJ379 coal mine safety monitoring system, but also with other types of coal mine safety monitoring systems, mining substations, and various power-off devices. The characteristics include stable performance, high sensitivity, high reliability, long service life, wide measurement range, good compatibility, and simple and convenient debugging.
