Connecting the Electrode and Temperature Probe
The waterproof pH 300/310 handheld pH meter uses any standard pH, ORP, or ISE electrode with a
BNC connector. For Automatic Temperature Compensation (ATC), this meter requires a
temperature probe with a special 6-pin connector.
Use either:
•
All electrode with a BNC connector and a separate temperature probe with 6-pin connector
(EC-PHWPTEM-01W/ 35618-05).
•
A “3-in-1” combination pH electrode with temperature probe designed specifically for pH 300
and pH 310 waterproof meters.
Refer to “Accessories” section on page 43 for more information on temperature probe and other
electrodes.
NOTE: Keep connectors dry and clean. Do not touch connector with soiled hands.
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.
5.
To remove electrode, push and rotate the connector counterclockwise. 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.
To connect the temperature probe:
1.
Line up the notch and 6 pins on the probe connector with the holes in the connector located on
the top of the meter. Push down and screw the metal sleeve to lock the probe connector into
place. See Figure 4.
6.
To remove probe, unscrew the metal sleeve and slide up the probe connector. While holding
onto metal sleeve, pull probe away from the meter.
CAUTION: Do not pull on the probe cord or the probe wires might disconnect.
