Product Introduction
Japan NEMOTO Catalytic Combustion Gas Sensor NAP-56A Description:
NAP-56A is the same as NAP-55A, mainly used for combustible gas leak alarms. Since no thermoplastic material is used, its high-temperature resistance is improved compared to NAP-55A. The pins are designed with interchangeability in mind, allowing it to replace NAP-55A in actual use. However, the corresponding gas sensitivity value is about 15% higher than NAP-55A, so necessary adjustments should be made when setting the alarm.
