ЭСКЛ-08М, ЭСКЛ-08М.1

Industrial (commercial) Glass electrodes

Glass combined laboratory electrodes  ESKL-08М, ESKL-08М.1 for рН measurement

ЭСКЛ-08М, ЭСКЛ-08М.1

Electrodes ESKL-08М, ESKL-08М.1 are designed for pH measurement in laboratory conditions (without use of reference electrodes). Combined laboratory electrodes ESKL-08М, ESKL-08М.1 – of general purpose with single-key integral reference electrode.

Application

Electrodes can be used for work operation with  devices I-160, I-160MP, рН-150M, рН-150MP, рХ-150MP, etc. Electrodes can be used by analysing with use of magnetic stirrer and by potentiometric titration.
