COMBINATION pH ELECTRODE EPS-1

Zoom

The EPS-1 combination glass body electrode is designed for pH measurements in clean liquids or liquids with low sediments content.
The electrode is distinguished by low impedance, short stabilisation period and a good linearity at the ends of the measurement range.
The electrolyte in the reference electrode is a 3 M KCl solution, which is refillable.
The electrode is equipped with a round glass membrane.
The ceramic electrolytical diaphragma (junction) is placed above the membrane.
The BNC-50 connector enables cooperation with majority of available pH meters.

The reference half cell is separated by an internal electrolytical diaphragma, what creates the ionic barrier. It prevents the silver ions from diffusion to the reference half cell, what in turn limits the chance of clogging of the ceramic diaphragma and interferences caused by the sulfide and cyanide ions from the measured solution. It also limits the interference caused by the reducing agents such as amines, buffers containing TRIS, sulfites, etc.
To keep the electrode permanently activated, it is equipped with a bottle filled with 3 M KCl put on its end, it should be taken off before the measurements. Such solution prolongs the electrode's life time. A special sealing ring protects from the electrolyte leakage from the bottle. The ring is tightened by screwing the bottle cap.
High quality at an affordable price.
