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.
