NCP-180S-6S

High Performance Catalytic Flammable Gas Sensor

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 header 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. For General purpose use in Industrial gas Detection Systems, we believe the NCP-180S-6S sensor to represent the best value gas sensor of its type on the market today.
