Analog controller for oxygen measurement
Excellent price/performance ratio - analog field monitor for the most varied applications in online oxygen measurement:
•User friendly and effective by easy handling
•Safe operation thanks to galvanically isolated outputs
•Reliable measurements by compressed air compensation and complete sensor monitoring
The Oxi 298 is an economical and metrologically flexible solution for use in the field. Galvanically isolated inputs and outputs are just as much standard as the complete function monitoring of the monitor and the connected sensor.
The connected oxygen sensor is continuously monitored for its function. In case of a defective membrane or in case of a used electrolyte, message is displayed and sent via the MODBUS interface.Model
