More Information
Summary:The invention refers to an electrochemical process measurement arrangement (10) with a process sensor unit (30), the sensor unit (30) comprising a reference electrolyte tank (50) with a reference electrolyte liquid (52) and a reference electrode (54), and a measurement electrolyte tank (60) with a measurement electrolyte liquid (62), a measurement electrode (64), a gas-selective membrane (90) separating the reference electrolyte liquid (52) from a sample liquid (13') and a pressure balance channel (84) fluidically connecting the tank interior (56) with the atmosphere (11).The pressure balance channel (84) is defined by a balance channel body (80) made of a hydrophobic material having a contact angle Theta higher than 90°.This allows to realize a very narrow pressure balance channel without the danger of being clogged by electrolyte droplets, so that the evaporation loss of the measurement electrolyte is significantly reduced.
