Contact combustion type gas sensor NAP-55A

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

NAP-55A is mainly used for gas alarms.In addition, this NAP-55A is about half the height and less than half the current consumption compared to the conventional sensor, so it is ideal for making the alarm device to be designed thinner and lighter.
