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.
