The Nemoto NP-17SH is a catalytic (pellistor) type flammable gas sensor supplied as a matched pair of pellistor elements mounted on a single header and protected by a stainless steel enclusure. The sensor detects and measures the presence of flammable gases and vapours in air, in the range 0-60% of the Lower Explosive Limit (LEL) of the gas or vapour being measured.

Designed to complement the NP-17SL, the NP-17SH has been designed for use in high temperature applications and may be used in temperatures up to 180 degrees C
