NE4-NH3 Range

Industrial  Ammonia (NH3) Sensors

General Description:

The NE4-NH3 range of sensors are an electrochemical gas sensors with 3 electrodes for the detection of Ammonia (NH3) in a variety of industrial and commercial gas detection applications. Exhibiting high performance with long-term stability, the compact (20.4mm dia) design 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 Options are available:              NE4-NH3 (0-100 ppm range)

                                       NE4-NH3-1000 (0-1000 ppm range)

                                                    NE4-NH3-5000 (0-5000 ppm range)
