1.2 pH Cube Side Panel and Connectors
pH / mV Connector
Used to connect pH, ORP (Redox) and Specific Ion sensors.
Ref Connector
Used to connect Reference sensor when a mono pH, ORP (Redox) 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.
