A p-type metal oxide H2S sensorH2S-A31 M31 P31Product Introduction

This sensor can respond well to extreme humidity and temperature environments in the oil and gas industry. In addition, the sensor is equipped with an integrated filtering device, which enables it toH2SSelective. Compared to commonnDifferent types of sensors, this metal oxide sensor has a large dynamic range, repeatable response, is less affected by humidity, and encountersH2SThe resistance will increase.
