Smart Ammonia Sensor

Smart Ammonia Sensor

Stox Smart Ammonia Sensor Device features a solid polymer electrochemical gas sensor with intelligent algorithms and a built-in microprocessor. It supports 4-20mA two-wire and RS485 Modbus RTU output. Designed for industrial safety, smart home, and IoT applications, it integrates temperature and humidity sensing and includes a self-test function for sensor performance without gas exposure. Each unit is factory-calibrated for real-time use with no warm-up time, storing calibration data in flash memory. Calibration software is available for signal adjustment. The device easily connects to displays, DCS, PLCs, and other systems.
