Product overview

The PHC201 series probe is a non-refillable, semi-liquid gel-filled combination pH probe

with a built-in temperature sensor (Figure 1). The standard PHC20101 or PHC20103 probe

comes with a 1 or 3 m (3.28 or 9.84 ft) cable and is intended for laboratory use. The probe

provides pH measurement in general aqueous applications. The probe is not suitable for

use with organic solvents, low ionic strength, wastewater, high solids or high alkaline sample

types.
