Stox – Smart Hydrogen Sensor Device

What is the Stox – Smart Hydrogen Sensor Device?

The Stox Smart Hydrogen Sensor Device is an intelligent Gas Sensor Device with a 4-20mA two-wire and 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. There is a calibration software from EC Sense in case a recalibration should be performed with the RS485 output or the 4-20mA output signal should be corrected. The Stox Gas Sensor Device has a standard 4-20mA two-wire or RS485 Modbus RTU output signal that allows for quick device and system setup or connection to a display, DCS, PLC and other systems

What Sensor Technology is used?

The heart of each Sensor Module is a solid polymer electrochemical sensor. This technology is a revolutionary innovation in the field of electrochemical detection. In essence this technology is based on the principle of electrochemical catalytic reaction. As a general rule the target gas generates a sensor signal which is direct proportional to the gas concentration. This is a basic electrochemical reaction. In addition to that the EC Sense solid polymer sensors are small, robust, reliable and above all do not consume any power.
