The Manning EC-FX-NH₃ ammonia sensor is designed for industrial refrigeration applications, delivering reliability, accuracy, and long-lasting performance in extreme conditions. It features a proprietary electrolyte that maintains sensitivity even during rapid temperature and humidity changes, and it recovers quickly after alarm-level gas exposure. The sensor operates in temperatures down to -50°F and 100% humidity with ATMOS Technology.

SensorCheck, a microprocessor function, verifies the electrical viability of the sensor every 24 hours, ensuring proper operation. The EC-FX-NH₃ outputs 4-20 mA (700Ω max impedance) and RS-485 Modbus RTU, and is available in NEMA 1 (PPO) or rugged stainless steel housings. It has a 3-year warranty and an average lifespan 18 months longer than competing sensors, reducing total cost of ownership. Applications include blast freezers, cold storage, and engine rooms.
