NCP-180SN

NC-180S-N gas sensor is a single header type ammonia gas sensor for industrial application, and it has been already available in many customers for fixed applications. 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.
