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.
