COMBINATION pH ELECTRODE EPS-2B

Zoom

The EPS-2B combination glass electrode is designed for pH measurements in liquids with small to medium contamination in the range 0 to 14 pH.
Working temperature up to 120°C.
EPS-2B is equipped with special thread for placing it in the immersion heads. The electrode is distinguished by the low impedance, short stabilisation period and good linearity at the ends of the measurement range.
The gel electrolyte is not refillable, but sufficient for all the exploitation period.
The ceramic electrolytical junction (diaphragm) is placed above the membrane of the electrode and it enables the contact between the measured solution and electrolyte in the reference electrode.
The electrode is equipped with a glass, hemispheric membrane.


The reference half cell is separated by an internal electrolytical diaphragm, 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 diaphragm 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.

High quality at a very affordable price as for electrodes resistant to high temperatures.
