General Description:

The NE4-H2S-200 is an electrochemical gas sensor with 3 electrodes for the detection of Hydrogen Sulphide (H2S) in a variety of industrial and commercial gas detection and process control 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.

​

Similar to the popular NE4-H2S-100 sensor, the NE4-H2S-200 has an extended detection range or 200ppm, enabling to be used in process control applications or in those areas where unusually high levels of H2S are likely to be regularly encountered.
