Intellical™ PHC101 is a digital combination pH electrode with built-in temperature sensor. PHC101 has low maintenance needs thanks to a non-refillable gel-filled single open reference junction. The laboratory version of this pH electrode is shockproff with its epoxy plastic body protecting down to the glass bulb sensing element. The Electrode is available with a 3 or 1 m cable. The PHC101 electrode is ideal for measuring pH in wastewater, drinking water and general aqueous applications. The PHC101 is not suitable for use with organic solvents or samples with pH less than 2.
