General Description:

The NE4-H2S-100 is an electrochemical gas sensor with 3 electrodes for the detection of Hydrogen Sulphide (H2S) in a variety of industrial and commercial gas detection applications.

​

Exhibiting high performance with long-term stability, this compact (20.4mm dia) sensor is suitable for portable Gas Detection Instruments or Fixed Gas Detection heads.  Nemoto's porous electrode technology enables accurate gas detection with high sensitivity.

​

The mechanical design of the sensor gives optimum gas diffusion characteristics, and the hermetically sealed enclosure prevents costly electrolyte leakage.

​

  •        3-Electrode design for greater stability

  •        Compact, leak-proof enclosure

  •        Resistant to shocks and vibration

  •        Linear output

  •        Highly specific to target gas

  •        Unaffected by humidity

  •        Low Power consumption

  •        Very Low Long term drift
