This unit includes an optional LCD display for local reading and is equipped with a built-in microprocessor for continuous sensor viability checking via SensorCheck™ technology. It supports a wide detection range from 0–100 ppm up to 1,000 ppm (with a high-range cell) and offers user-configurable output through isolated 4/20 mA and RS-485 Modbus RTU. With rugged construction and optional enclosures for extreme conditions, the EC-F9-NH3 ensures reliable detection in challenging environments. Key Features: Electrochemical Sensor: Utilizes diffusion-based electrochemical detection for accurate NH₃ monitoring. Multiple Ranges Available: Supports 0–100, 0–250, 0–500, and 0–1,000 ppm ranges depending on configuration. SensorCheck™ Viability Test: Self-diagnostic feature checks sensor functionality every 24 hours. Flexible Output Signals: Provides isolated 4–20 mA analog output and RS-485 Modbus RTU communication. Optional LCD Interface: 2-line by 8-character alphanumeric display with backlight and dual push-button control. Wide Environmental Tolerance: Operational range from -50°F to +120°F with condensing humidity up to 100%. NEMA 1 Steel Enclosure: Gasketed steel housing; stainless steel or explosion-proof versions available. Simple Cabling: Accepts standard shielded cables for output, communication, and power up to long distances. The EC-F9-NH3 delivers the reliability and safety required for continuous ammonia gas monitoring in industrial environments.
