7.2 pH probe
The pH probes are shipped with a wetting cap that covers the probe tip. Remove the cap
by turning it counter-clockwise and gently easing it off. Keep this cap for long-term probe
storage. Rinse the probe tip with distilled water.
Store the probe in a pH 4.0 buffer (Cat. No. 2104) for both overnight and long term
storage. Never store a probe in distilled or deionized water because this will deplete the
probe filling solution.
7.2.1 pH probe connection
This connector is for installing the pH or ORP pre-amp interface junction box or a
stand-alone temperature sensor. The pH probe is attached to a terminal strip in the
junction box. The stand-alone temperature probe plugs directly into the receptacle on the
case.The pre-amplifier junction box is provided to allow for fast, easy replacement of the
pH probe.
