3.2 Probe
Information
Your meter includes two probes:
•
pH electrode with BNC connector.
•
conductivity/temperature
probe
with a notched 6-pin connector
The temperature sensing element built into the conductivity probe will also compensate
for pH readings as long as both probes are in your solution at the same time.
If you want to use a “3-in1” pH probe with a built-in temperature element, or if you want to use
a separate temperature probe, you will need to disconnect the conductivity probe to allow for
connection of the separate temperature sensor.
You can use any standard pH electrode with a BNC connector with this meter. Conductivity
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.
NOTE:
Keep connector 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 anti-clockwise. While holding onto
the metal part of the connector, pull it away from the meter.
CAUTION:
Do not pull on the probe cord or the probe wires might disconnect.
