NAP-50A N50A Gas Alarm Japan Catalytic Combustion Sensor For Various Gas Concentration Meters
NAP-50A is a miniature & low power consumption type of NAP-2A, and 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-2A for measuring circuit for sensor evaluation.
