NH3-B1 Four Electrode Electrochemical Ammonia Sensor Electrochemical Gas Sensor For Detect The Concentration Of Ammonia In The Atmosphere Linear Current Output Easy Signal Processing

NH3-B1 Four Electrode Electrochemical Ammonia Sensor Electrochemical Gas Sensor For Detect The Concentration Of Ammonia In The Atmosphere Linear Current Output Easy Signal Processing

NH3-B1 Ammonia Sensor NH3 Sensor Description
Alphasense is expanding its line of electrochemical toxic gas sensors to address industry-specific requirements, including emissions monitoring, process safety, environmental monitoring and VOCs.

Ammonia (NH3)
Our first family of Ammonia sensors. This sensor is designed for higher concentrations of Ammonia. Sensors for lower level detection are in development.
