A P-type metal oxide H2S sensor H2S-A31 M31 P31 product introduction

The sensor responds well in the extreme humidity and temperature environments of the oil and gas industries and is equipped with an integrated filtration unit that makes it selective for H2S. Unlike common n-type sensors, this metal oxide sensor has a large dynamic range, a repeatable response, little humidity effect, and an increased resistance to H2S.

The sensor is available in 3 housings: TO-05 housing, 6-pin plastic housing and Ex explosion-proof housing.
