NAP-57A N57A Catalytic Combustion Of Combustible Gas Sensor Probe It Can Be Used In Industrial And Commercial Flammable Gas Detectors And Has Good Detection Sensitivity In Toxic Gas Environments Such

NAP
57 A is a newly developed catalytic type gas sensor based on conventional
type NAP 56A for not only residential but also commercial or semi industrial
application s because of having highly excellent poisoning resistivity S ince its
power cons umption and pin position s are completely th e same as NAP 55A and
56A , it is easily replaceable as it is However, it does not possess the explosion
proof by itself, then it is recommended to install it into an explosion proof
chamber for actual application

1. Features and usage of NAP-57 A
1) Features:

Good stability

Excellent repeatability and detection accuracy

Good linearity against gas concentration at wide range

Quite excellent poisoning resistivity

Down sizing for design flexibility of gas alarm or det ector
2) Usage:

Gas alarm or detector of general combustible gases for all applications

Gas densitometer

Driving module for gas leakage detector
