OXY-LC-485

OXY-LC-485 is a oxygen sensor interface board. It provides all necessary electronics to power and control SST Sensing’s range of dynamic oxygen sensors. It features communications via RS485 Modbus RTU protocol allows complete control of the sensor operation and access to all available sensor information including diagnostics. Fast sensor response coupled with a very stable oxygen concentration output is achieved through adaptive software filtering. The oxygen sensor and interface can be calibrated in normal air (20.7% O2) or in any other known O2 concentration. A software delay of 5 minutes from sensor heater being enabled prevents calibration before sensor has reached a stable operating temperature. Adjustable communication settings including the ability to change the slave address of the interface allows up to 32 interfaces to communicate on the same bus. Suitable for laboratory & building air quality monitoring including confined space personnel safety.
