Product Specification

NAP-66A is mainly used for gas detectors and leak testers. NAP-66A is a half in height and needs a half in power consumption compared to existing sensor so that thinner and lighter-weight detectors can be produced. The following are the basic characteristics but it is recommended to refer to the individual user’s manual for further information.

* Target gases and concentration

Gases		Detection range
Propane	C3H8	0.03~ 2.2% (0.03~ 1%)
Iso-butane	Iso-C4H10	0.03~ 1.8% (0.03~ 0.8%)
Hydrogen	H2	0.05~ 4% (0.05~ 1.5%)
Ethanol	C2H5OH	0.05~ 3.2% (0.05~ 1.5%)
Hydrocarbons	CnH2n+2	1~100% LEL (1~50%LEL)

( ) is a detection range in high accuracy
