Section 1 Product overview
The Intellical PHC745 pH probes are digital, combination electrodes that measure the pH of water
samples. The glass sleeve junction keeps the reference junction clean for measurements in
wastewater influent, emulsions and viscous liquids. The probes use the Red Rod technology and a
saturated KCl electrolyte for high performance. The probes are refillable and have a built-in
temperature sensor. A 59-mL bottle of reference electrolyte filling solution (saturated KCl solution) is
supplied with the probe. Refer to
Figure 1 .
Note: Do not use the probe to measure the pH of organic solvents or very alkaline samples.
