Section 1 Product overview
The Intellical PHC301 series pH probes are digital, combination electrodes that measure the pH of
wastewater, drinking water and general water samples. The probes are refillable and have a built-in
temperature sensor and a double ceramic pin for a reference junction. A 28-mL bottle of reference
electrolyte filling solution is supplied with the probe. Refer to
Figure 1 .
Note: Do not use the probe for measurements in organic solvents.
