Section 1 Product overview
The Intellical PHC101 series pH probes are digital, combination electrodes that measure the pH of
wastewater, drinking water and general water samples. The probes have a non-refillable, gel-filled
electrolyte and a built-in temperature sensor. The open reference junction gives an optimum
electrical connection between the sample and the electrolyte and does not become clogged. The
standard probes are for laboratory use. The rugged probes are for field use. Refer to Figure 1.
Note: Do not use the probe to measure the pH of organic solvents or samples with a pH less than 2.
