NCP-180-H gas sensor is a matched pair type hydrogen gas sensor for industrial application, and it has been already available also in many customers for fixed applications. Since this type does not meet the structure of explosion proof by itself, it has to be installed in the approved body by ATEX, CSA or etc.

* : 「-」 means that it is not a detected gas.
** : R.S. (relative sensitivity) is described in case that sensitivity to hydrogen is 100.
