NCP-50SNCP-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. Dimensions
