NCP-70S 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.

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