Product Overview
The Ammonia Gas Sensor Probe NH3-500-Probe utilizes Solid Polymer Electrolyte and coulometry for high-precision ammonia detection. Designed for continuous operation in high ammonia concentrations, it offers a long lifetime and eliminates the need for calibration due to its electrochemical reaction and integrated pump. This probe is ideal for livestock farms, industrial ammonia leakage detection, and cooling storages. Its RS485 (Modbus) output seamlessly integrates with gas detectors, DCS, PLCs, and wireless systems. The sensor automatically adjusts its detection range from ppb to ppm levels and features automatic fault checking.
