To connect the pH 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 dissolved oxygen probe:
NOTE: Do not substitute other DO probes. For a replacement DO probe, see the
“Accessories” section, page 64.
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.

Probe information
Your meter uses two probes:
• pH electrode with BNC connector
• dissolved oxygen/temperature probe with a notched 6-pin connector
The temperature sensing element built into the dissolved oxygen probe will also
compensate for pH readings as long as both probes are in your solution at the
same time.
You can use any standard pH electrode with a BNC connector with this meter.
If you do not have the DO probe connected you will need temperature probe
35618-05 to provide temperature compensation for pH readings (not included
order separately). For the dissolved oxygen/temperature probe, you must use an
OAKTON dissolved oxygen/temperature probe with the notched 6-pin connector.
For replacement probes, see the “Accessories” section, pages 64-65.
NOTE: Keep connectors dry and clean. Do not touch connectors with soiled hands.
