carbon monoxide gas sensor NAP-505

  • For consumer
  • Consumer alarm
  • Underground parking alarm
  • Generator
  • Electrochemical formula
  • Carbon monoxide
  • UL Recognition Mark Acquired Products

NAP-505 is an electrochemical CO gas sensor that is significantly smaller than other electrochemical CO sensors. In particular, with a thickness of approximately 2034 mm, it is the smallest electrochemical sensor for consumer use in the world. The detection principle is the same as that of general electrochemical gas sensors, but by improving the structure and electrodes, we have achieved a type that can be supplied at a low cost while maintaining performance. It is ideal for CO alarms for general households, and has also obtained UL2075 XNUMX component certification.

Electrochemical gas sensor NAP-508

  • For consumer
  • Consumer alarm
  • Underground parking alarm
  • Generator
  • Electrochemical formula
  • Carbon monoxide
  • UL Recognition Mark Acquired Products

The newly developed NAP-508 electrochemical CO sensor is a consumer electrochemical CO gas sensor with a longer life than the conventional NAP-505 sensor. The shape and dimensions are exactly the same as the conventional NAP-505 sensor, but the cap is dark blue to distinguish it from the conventional product. Based on the results of accelerated life expectancy prediction tests, the sensor is expected to last approximately 12 years under actual usage conditions. It has excellent performance, and can be installed in general home appliances and fire alarms that have not been installed until now. Due to the high heat resistance of the plastic material used, it can also be installed in exhaust gas monitors of latent heat recovery type combustion appliances.

Electrochemical gas sensor NAP-550

  • For consumer
  • Consumer alarm
  • Underground parking alarm
  • Electrochemical formula
  • Nitrogen dioxide

NAP-550 is an electrochemical gas sensor for detecting nitrogen dioxide, which is a gas sensor developed for underground parking lot alarm applications. Since the detection gas of the 50 series is an oxidizing gas, the output signal is generated on the opposite side, unlike general reducing gas.In addition, it selectively has sensitivity only to NO2 or N2O4, which have oxidizing power in NOx, and does not detect all NOx.

Measurement range
Nitrogen dioxide / NO2 0-30ppm
Detection target gas
Nitrogen dioxide / NO2

Heat conduction gas sensor NAP-21A

  • For consumer
  • Consumer alarm
  • Heat conduction type
  • carbon dioxide

NAP-21A is sensitive to carbon dioxide and inert gas, and can be used even in an oxygen-free environment.Since it is easily affected by changes in temperature and humidity, it is ideal for monitoring the concentration in a closed environment such as an incubator or incubator.

Measurement range
Carbon dioxide / CO2 2-100%
Detection target gas
Carbon dioxide / CO2

Contact combustion type gas sensor NSU-131A
