Contact combustion type gas sensor NAP-78SU
- For consumer
- Consumer alarm
- Water heater / boiler
- Contact combustion type
- Incomplete combustion exhaust gas
NAP-78SU is a gas sensor developed to detect incomplete combustion of gas water heaters. It can directly detect exhaust gas at about 200 ° C and is sensitive to carbon monoxide and hydrogen.A bridge circuit is built on the board, and it can be adjusted to any zero point with a variable resistor.
- Measurement range
- Incomplete combustion exhaust gas within 1% * Contains 0.5% hydrogen
- Detection target gas
- Incomplete combustion exhaust gas
Contact combustion type gas sensor NAP-80S
- For consumer
- Consumer alarm
- Water heater / boiler
- Contact combustion type
- Incomplete combustion exhaust gas
NAP-80S is a type of gas sensor with improved hydrogen durability of NAP-78SU.Conventional sensors could fail if exposed to hydrogen gas above LEL, but this sensor is completely unaffected and can detect repeatedly.

The hydrogen alarm (NDR-H2-1A) detects leaked gas and alerts the surrounding area of the danger of gas leakage. A buzzer and LED lamp alarm will be activated when the threshold is 500ppm. The power supply is AC100V, and an A contact relay is provided as an external output. It can be used in a variety of ways, from simple installation to interlocking devices. Application examples: gas chromatography, hydrogen cutting, hydrogen generators, near hydrogen cylinders, etc.
- Measurement range
- 500 to 20,000ppm (range error 15%)
- Detection target gas
- hydrogen
