The Nemoto NP-17SL 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 enclosure. The sensor detects and measures the presence of flammable gases and vapours in air, in the range 0-100% of the Lower Explosive Limit (LEL) of the gas or vapour being measured.

Designed as an improved version of the established NP-17S sensor, the NP-17SL exhibits very similar performance characteristics to the twin header NP-17 sensor.
