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.
