Electrochemical gas sensor NE4-HCHO-S

  • Industrial
  • Industrial alarm
  • Indoor environment
  • Electrochemical formula
  • Formaldehyde

NE4-HCHO is an electrochemical gas sensor for formaldehyde detection, and since it has a large output current, it can detect it with high accuracy even at low concentrations.It can be applied to a wide range of applications such as detection of building material odor.

Measurement range
Formaldehyde / HCHO 0-10ppm
Detection target gas
Formaldehyde / HCHO

Electrochemical gas sensor NAP-505

  • For consumer
  • Consumer alarm
  • Underground parking alarm
  • Generator
  • Electrochemical formula
  • Carbon monoxide

NAP-505 is a small electrochemical carbon monoxide gas sensor.The detection principle is the same as that of a normal electrochemical gas sensor, but by devising the structure and electrodes, we have realized a type that can be supplied at low cost while maintaining performance.It is ideal for general household CO alarms and has been certified as a part of UL2034 2075.

Measurement range
Carbon monoxide / CO 0-1000ppm
Detection target gas
Carbon monoxide / CO

Electrochemical gas sensor NAP-508

  • For consumer
  • Consumer alarm
  • Underground parking alarm
  • Generator
  • Electrochemical formula
  • Carbon monoxide

The NAP-508 has the same shape as the NAP-505 and is a newly developed carbon monoxide sensor as its long-life type.Based on the results of long-term tests and various life prediction acceleration tests, it can be installed in general household appliances and fire alarms, which have been postponed until now, as sensors that can guarantee a life of 12 years in actual use environments. It has excellent performance such as being able to do it.In addition, due to the high heat resistance of the plastic material used, it can also be installed in the exhaust gas monitor of latent heat recovery type combustion equipment.

Measurement range
Carbon monoxide / CO 0-2000ppm
Detection target gas
Carbon monoxide / CO

Electrochemical gas sensor NAP-520

  • For consumer
  • Consumer alarm
  • Disaster countermeasure measuring instrument
  • Special purpose measurement Combustion exhaust measuring instrument
  • Electrochemical formula
  • Hydrogen sulfide

NAP-520 is an electrochemical gas sensor for detecting hydrogen sulfide and can be used for various gas detectors.It has high performance, high stability and small size, and is suitable for portable devices that can be carried by workers.

Measurement range
Hydrogen sulfide / H2S 0-100ppm

Electrochemical gas sensor NAP-523

  • For consumer
  • Consumer alarm
  • Disaster countermeasure measuring instrument
  • Special purpose measurement Combustion exhaust measuring instrument
  • Electrochemical formula
  • Hydrogen sulfide

NAP-523 is a 3-electrode type electrochemical gas sensor developed to detect hydrogen sulfide.This sensor is highly sensitive and has extremely high selectivity for hydrogen sulfide.Due to the small size of this sensor, it is a gas sensor that can be mounted on portable devices such as bad breath checkers.

Measurement range
Hydrogen sulfide / H2S 0-0.5ppm
Detection target gas
Hydrogen sulfide / H2S

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
