Contact combustion type gas sensor NAP-50AF

For consumer
Consumer alarm
Contact combustion type
Combustible gas (for city gas)

NAP-50AF is a type of gas sensor in which NAP-50A is filtered with activated carbon.Durability is improved by suppressing the influence of miscellaneous gas in the environment with an activated carbon filter.
