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 AQ 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.
