NE7-H2S
Electrochemical Hydrogen Sulfide (H2S) Gas Sensor

General Description:

The NE7-H2S is a new electrochemical gas sensor with 3 electrodes for the detection of Hydrogen Sulfide (H2S) in a variety of industrial and commercial gas detection and Environmental monitoring applications.

​

Exhibiting high performance with long-term stability, this compact (32mm 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.
