Overview The Stox Smart Ammonia Sensor Device is an intelligent sensor device from EC Sense, which has a 4-20mA two-wire and a RS485 Modbus RTU output signal. It uses an intelligent microprocessor with high-reliability solid polymer electrochemical gas sensor technology and intelligent algorithm calculation. The Stox Device is a smart solution for industrial safety applications, combining temperature and humidity in one sensing device. The intelligent Gas Sensor Device provides a self-test, which evaluates the sensor performance without a gas measurement. Therefore, it is the excellent solution for smart home and IoT applications. The data is put out through the the output signal or RS485 transmission command, which makes it easy and convenient to identify the right time to perform maintenance and replacement. Each Stox Sensor Device has been professionally calibrated with the gas. It can be instantly used without prior warm-up time and the calibration information is stored in the flash chip.
