Product overview
The probe is a digital pH combination electrode with refillable electrolyte, a glass body
and an integrated temperature sensor. The probe is for laboratory use and measures pH
in general aqueous samples.
Note: Do not use the probe with organic solvents, low ionic strength, wastewater, high solids or
high alkaline sample types.
A 50-mL bottle of reference electrolyte filling solution (3 M KCl solution) is included with
the probe. Refer to
Figure 1 .

Preparation for use
Prepare the probe before a calibration or a sample measurement.
1. Turn the probe soaker bottle cap counter-clockwise to loosen the cap.
2. Remove the soaker bottle from the probe.
3. Fully rinse the reference junction and the glass bulb with deionized water to remove
all of the storage solution or possible salt particles. Dry with a no-lint cloth.
4. Remove the protective tape from the filling hole before initial use (refer to Product
overview on page 2). Discard the protective tape.
