Nemoto NAP-55A Catalytic Flammable Gas Sensor, Sensor Only
NAP-55A (NAP55A) is a Nemoto catalytic flammable-gas sensing component. This listing is for the sensor only, not a complete portable detector, alarm or ready-to-use detector module.
Application and selection
The manufacturer's model reference covers methane/natural-gas detection in the 0-50% LEL range. The sensor requires suitable detection circuitry and gas-specific calibration; a response to a gas does not establish interchangeable calibration for every flammable gas.
Match the equipment's required sensor model and electrical interface. Confirm the actual label, production batch and applicable datasheet revision when operating limits are critical; the listing's reference graphics are not a batch certificate. Follow the equipment manufacturer's installation, calibration and response-test instructions before use.
