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.

Measurement range
Incomplete combustion exhaust gas within 1% * Contains 0.5% hydrogen
Detection target gas
