pH and ORP controller, PH3030

pH and ORP controller, PH3030

Product description

pH and ORP analyzer

The controller can be configured to measure pH and ORP during the installation. It provides manual and automatic temperature compensation, if a Pt100 is connected. When the RTD is connected, the instruments provides the temperature reading.
