Honeywell Analytics/Manning Systems EC-F9-NH3 Ammonia Gas Detection Sensor

Honeywell's EC-F9 electrochemical cell is a three-electrode sensor designed for rapid response measurement of ammonia concentrations in ambient air. Its gas diffusion detector is designed for excellent zero and calibration stability over long periods of time. EC cells often last three to four years in the refrigerated environments of food processing and storage warehouses.

This sensor can provide direct input into PLCs and other control systems that accept a linear 4-20 mA signal, either directly from the sensor or from any Manning multichannel alarm consoles with relay or analog output. Its easy-to-read optional LED display allows for quick visual error events at startup and troubleshooting and can be calibrated without a voltmeter. The EC-F9-NH3 with LCD is designed to work in the harshest environments including chemical washdown.
