KG9701A Mining low concentration methane sensorDetailed product description：

The KG9701A low concentration methane sensor is mainly used for measuring gas concentration in environmental gases and is an essential measuring instrument for preventing gas outbursts and explosions in coal mines. It can continuously and automatically convert underground biogas into standard electrical signals and transmit them to relevant equipment, and has functions such as on-site display of gas concentration values and over limit sound and light alarms. Adopting the achievements of the national "Ninth Five Year Plan" research and development project: high stability, long-life thermal catalytic elements, the performance indicators of the catalytic elements have been greatly improved by changing the manufacturing process and catalyst formula. The use of artificial intelligence technology to process and analyze information has enhanced the instrument's ability to resist shock waves. It has the characteristics of stable performance, accurate measurement, fast response speed, sturdy structure, and easy use and maintenance. It has added new functions such as remote control calibration, power-off control, and fault self checking, greatly saving the cost of use and maintenance.
