3.2 Probe Information
Your meter includes two probes:
• pH electrode with BNC connector.
• DO/temperature probe with a notched 6-pin connector
The temperature sensing element built into the DO 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. DO probes, “3-
in-1” pH electrodes with a built-in temperature element, and temperature probes require a
notched 6-pin connector (see Figure 4). For replacement probes, see the Accessories section.
If you want to use a “3-in-1” pH probe with a built-in temperature element, or if you want to use
a separate temperature probe, you will need to disconnect the DO probe to allow for
connection of the separate temperature sensor.
NOTE: Keep connectors dry and clean. Do not touch connector with soiled hands.
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.
2. To remove electrode, push and rotate the connector counterclockwise. While holding
onto the metal part of the connector, pull it away from the meter.
See Figure 4.
CAUTION: Do not pull on the probe cord or the probe wires may be damaged.
