COMBINATION pH ELECTRODE EPP-1
The EPP-1 combination plastic body electrode is designed for pH measurements in liquids without deposits. The electrode is distinguished by low impedance, short stabilisation period and a good linearity at the ends of the measurement range. Plastic body protects from braking. The gel electrolyte is not replaceable but makes using the electrode easier. The electrode has a round glass membrane. Next to the membrane a ceramic junction which enables the contact of the measured liquid with the electrolyte was placed. The BNC connector enables using the electrode with most of the pH meters. The EPP-1 does not require separate activation because it is equipped with a bottle filled with 3 M KCl put on its end and taken off before the measurements. Such solution makes the electrode permanently activated and prolongs its life time. A special sealing ring protects from the electrolyte leakage from the bottle. The ring is tightened by screwing the bottle cap.
