Section 1 Product overview
The Intellical PHC108 pH probe is a digital, combination electrode with a cone-shaped glass sensor
that measures the pH of semi-solid samples, emulsions and slurries (e.g., soil, mud, sludge, foods).
The probe is non-refillable and has a built-in temperature sensor, ceramic pin and open reference
junctions. Refer to
Figure 1 .
Note: Do not use the probe to measure the pH of organic solvents, low ionic strength samples or very alkaline
samples.
