NE4-O3

Electrochemical Ozone (O3) Gas Sensor

General Description:

The NE4-O3 is an electrochemical gas sensor with 3 electrodes for the detection of Ozone (O3) in a variety of industrial and commercial gas detection and Environmental monitoring 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.
