B&C Electronics PH 7635 pH or ORP analyzer
The controller can be configured to measure pH or ORP during the installation.
It provides manual and automatic temperature compensation, if an RTD Pt100 or an RTD Pt1000 is connected.
When the RTD is connected, the instruments provides the temperature reading.
