Ammonia Gas Sensor

ECtox ammonia detection devices feature a durable EC Sense solid electrolyte NH3 sensor offering long life, selectivity, and high-precision detection. Unlike common sensors that degrade quickly in high ammonia environments, ECtox maintains performance and longevity. Using a specific electrochemical reaction and a sample pump, it measures a wide ammonia concentration range without calibration. The adaptable sampling system compensates for variations in diffusion and convection speeds due to environmental factors. Output via RS485 (Modbus) allows easy integration with gas detectors, DCS, PLC, or wireless systems.
