ЭВЛ-1M4

ЭВЛ-1M4 - an electrode is used to create the reference potential for potentiometric measurements. The electrode is designed to connect to the devices I-102, pH 125, pH-150, CP-1.

If the resulting solution of KCl electrode is interfering, offer electrode ЭВЛ-1M4 install the electrolytic cell 1E5.184.307 type of solution poured into the key (cell), are defined by reference to the ED to the applicable measuring electrodes. In such measurements the measuring electrode is placed in a glass of the control solution directly, and the auxiliary electrode by electrolytic key (cell).

1E5.184.307 electrolytic cell produced by the plant.
