General Description:

The Nemoto NCP-180S-6S is a catalytic (pellistor) type flammable gas sensor supplied as a matched pair of elements mounted on a single headers and protected by a metal mesh.  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. The sensor is primarily designed for use within Fixed Gas Detection Systems.

The NCP-180S-6S is designed to bring together the performance levels normally expected from Twin Header devices with the cost benefits of single header design. As such we believe the NCP-180S-6S sensor to represent the best value gas sensor of its type on the market today.
