1.2 pH Cube Side Panel and Connectors
pH / mV Connector
• Used to connect pH, Redox (ORP) and Specific Ion sensors.
Ref Connector
• Used to connect Reference sensor when a mono pH, Redox (ORP) or
Specific Ion sensor is connected to the pH / mV Connector.
Temp Connector
• Used to connect Temperature sensor. This sensor provides temperature
readout as well as Automatic Temperature Compensation for pH readings.
Temp Cal Control
• Used for temperature calibration. See section 5.
12V DC Power Connector
• Used to connect 12V AC/DC Adaptor. The pH Cube can run off any 12V
DC source with at least 200mA output. The 12V DC connector has a
positive tip.
