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.
【Feature】
- The sensor is stable
- High detection accuracy and high reproducibility
- Good linearity with respect to gas concentration
- Responsive
- Because it is small, there is a high degree of freedom in designing gas alarms and detectors.
- Low power consumption
- 【Example of use】
- Gas alarms and detectors for detecting flammable gases
- Gas concentration meter
- Gas leak detector module
