DESCRIPTION

The Manning EC-F9-NH3 sensor consists of a pair of polarised electrodes isolated from the ambient air by a gas permeable membrane. As Ammonia diffuses into the sensor, a redox reaction occurs, generating a current linearly proportional to Ammonia gas concentration. Unlike many other Ammonia sensors, this gas diffusion detector exhibits excellent zero and calibration stability over long periods of time. EC cells often last 3-4 years in the refrigerated environments of food processing and storage warehouses. This sensor can provide direct input into PLC’s and computer control systems that accept a linear 4/20 mA signal either directly from the sensor or from any Manning mulitchannel stand alone alarm consoles with relay or analogue output.
