Product overview
The PHC301 series probe is a pH refillable combination probe with a built-in temperature
sensor (
Figure 1 ). The PHC30101 or PHC30103 probe is available with a 1 or 3 m
(3.28 or 9.84 ft) cable and is intended for laboratory use. The pH refillable combination
probe measures pH in wastewater, drinking water and general aquous applications. The
probe is not suitable for use with organic solvents. A 28-mL bottle of reference electrolyte
filling solution (3 M KCl solution saturated with AgCl) is included with the probe.
