The measuring electrodes should be connected to the corresponding coaxial pH/mV or EC connectors. Automatic temperature compensation and temperature measurements are possible by plugging a Pt1000 temperature probe into the °C terminals. Without Pt1000, the manual temperature compensation is automatically switched on. | The measuring electrodes should be connected to the corresponding coaxial pH/mV or EC connectors.
