NT-NH3 Electrochemical Ammonia Sensor
ELECTROCHEMICAL AMMONIA SENSOR, THE NT-NH3 FROM NEMOTO & Co Ltd WORLD LEADERS IN GAS SENSOR TECHNOLOGY (http://www.nemototech.com/)
Nemoto & Co manufactures and markets a range of Gas Sensor Devices for use by Gas Detection and Gas Analysis Instrument manufacturers worldwide. They do not manufacture complete instruments, but offer high quality Gas Sensing devices, technical support and commercial partnership to those companies who do.

General description of the sensor

The NT-NH3 Cell is a new electrochemical gas sensor with 3 electrodes for the detection of Ammonia (NH3) in a variety of gas detection applications. Exhibiting high performance with long-term stability, The compact (20.4mm dia) NT-NH3 sensor is designed to monitor toxic levels of ammonia is a wide variety of industrial safety applications. The sensor is mechanically and electrically compatible with a wide variety of commercially available gas detection instruments
