The Pt100 temperature sensor can be connected to Fibox 4, Microx 4 and OXY-1 series oxygen meters. It can be used to determine the temperature during experiments and for automatic temperature compensation of the oxygen measurements. It is recommended to connect a temperature sensor to the oxygen meters when temperature changes are expected during experiments, to ensure correct temperature compensation and precise oxygen measurements. https://agg-blackbox.com/Instrumentation/Pt100-Temperature-Sensor
