Connecting the Electrode and Temperature Probe
The OAKTON pH/mV meter can use any standard pH, ORP, or ISE electrode with a BNC connector. For automatic temperature compensation (ATC), this meter requires a temperature probe with a specialty 6-pin connector. Use either: • any electrode with a BNC connector and a separate temperature probe with
6-pin connector (part number 35618-05)
• an “All-in-One” combination pH electrode/temperature probe designed
specifically for the pH 300 and pH 310 waterproof meters
NOTE: Keep connectors clean. Do not touch connector with soiled hands. See the “Accessories” section on page 45 for a temperature probe and “All in One” electrodes for use with the pH 300 and pH 310 meters.

To connect the pH, ORP or ISE electrode: 1. Slide the BNC connector of the probe over the BNC connector socket on the
meter. Make sure the slots of the connector are in line with the posts of the socket. Rotate and push the connector clockwise until it locks.
See figure below.
2. To remove probe, push and rotate the connector counterclockwise. While
holding onto the metal part of the connector, pull probe away from the meter.
CAUTION: Do not pull on the probe cord or the probe wires might disconnect.
To connect the temperature probe: 1. Line up the notch and 6 pins on the meter with the holes in the 6-pin connector.
Push down and turn the locking ring clockwise to lock into place.
See figure below.
2. To remove probe, turn the locking ring counterclockwise on the probe connector.
Pull probe away from the meter.
CAUTION: Do not pull on the probe cord or the probe wires might disconnect.
