Contact combustion type gas sensor NAP-55A
- For consumer
- Contact combustion type
- Combustible gas (for city gas)
- UL Recognition Mark Acquired Products

NAP-55A is a gas sensor for combustible gases. It has excellent output linearity for combustible gas concentrations below 100% LEL. It has even better linearity when the concentration is below 50% LEL. Furthermore, NAP-55A is about half the height and consumes less than half the current compared to conventional sensors, making it ideal for designing thinner and lighter alarms.

Contact combustion type gas sensor NSU-131AF
- For consumer
- Consumer alarm
- Fuel cell
- Contact combustion type
- Combustible gas (for city gas)

NSU-131AF is a highly durable consumer sensor module with an activated carbon filter added to NSU-131A.Since it is sensitive to hydrogen and methane gas, it can be used for city gas.It is mainly used for stationary household fuel cells.

Contact combustion type gas sensor NSU-131AF2
- For consumer
- Consumer alarm
- Fuel cell
- Contact combustion type
- Combustible gas (for city gas)

NSU-131AF2 is the latest sensor module with high durability, which has an increased amount of NSU-131AF activated carbon filter.It has a longer life due to the increased characteristics of miscellaneous gas.

Contact combustion type gas sensor NAP-50A
- For consumer
- Consumer alarm
- Contact combustion type
- Combustible gas (for city gas)
- UL Recognition Mark Acquired Products

The NAP-50A is smaller and consumes less power than our previous catalytic combustion gas sensor, consuming approximately 55% less power than the previous catalytic combustion gas sensor. In addition, it has a lower alcohol sensitivity than the same model NAP-XNUMXA, so it is used in gas alarms for both home and commercial use. It also has excellent response to gas.

Contact combustion type gas sensor NAP-51A
- For consumer
- Consumer alarm
- Contact combustion type
- Combustible gas (for city gas)

Like the NAP-51A, the NAP-50A is a model with reduced alcohol sensitivity.False detection due to alcohol used in disinfection and cooking can be suppressed. Gas sensitivity is about 50 times higher than NAP-1.6A.

Contact combustion type gas sensor NAP-56A
- For consumer
- Consumer alarm
- Contact combustion type
- Combustible gas (for city gas)

Like the NAP-56A, the NAP-55A is a gas sensor suitable for detecting city gas leaks. Gas sensitivity is 55 to 1.2 times higher than NAP-1.5A, making it easy to design.

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.
