2.3.3 Connecting pH/ORP Electrode

1. If the pH/ORP electrode has a BNC connector, remove the BNC

connector from the cable.

NOTE: Oakton Instruments offers an optional ‘BNC to Spade Lug

adapter’ (Order code: 05994-90) that can be used with pH/ORP

electrode without removing the BNC connector.

2. Strip the insulation of the cable so that the bare wires are exposed

enough for connection as shown in Figure 3.
