NIS-02C

NCP-50S

NCP-50S gas sensor is a single header type for industrial application, and it has been already available also in many customers for handheld, wearable or portable applications.

Since this type has a simplified explosion proof structure, however it is recommended that it is installed in the approved body by ATEX, CSA or etc.
