Product Specification

NAP-50A is a miniature & low power consumption type sensor. NAP-50A is mainly used for gas detectors. Compared to NAP-55A, NAP-50A has a lower alcohol sensitivity to eliminate false alarms caused by alcohol, thus more reliable gas detectors can be produced with NAP-50A. The following are the basic characteristics but it is recommended to refer to the individual user’s manual for further information. See NAP-66A for measuring circuit for sensor evaluation.

* Target gases and detection range

Gases		Detection range
Methane	CH4	0.05~ 5% (0.05~ 2%)
Ethane	C2H6	0.05~ 3.2% (0.05~ 1.5%)
Iso-butane	Iso-C4H10	0.03~ 1.8% (0.03~ 0.8%)
Hydrogen	H2	0.05~ 4% (0.05~ 1.5%)
Hydrocarbons	C_nH_2n+2	1~100% LEL (1~50%LEL)

( ) is a detection range in high accuracy
