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%) | |||
