NE4-H2S-500

NE4-H2S

NE4-H2S is a hydrogen sulfide gas sensor for industrial applications, and 3 types except standard type (H2S-100, H2S-200 and H2S-500) are also available as described in the next page.
The most suitable type can be easily selected according to the applications.
Output current is fairly large, it means that it can detect fairly low concentration of hydrogen sulfide, and additionally, since it has excellent selectivity, resistivity and responsibility, it is applicable in wide applications.
By adhering to industry standards for size and connection orientation, the NE4-H2S can be retrofitted easily to existing product designs.
