The instrument uses streaming current technology to produce
a measurement of electrokinetic charge (ionic & colloidal)
using a sample obtained from various points in the process
(Headbox, Coated Broke, Machine Chest, Tray Water, etc..).

Although the streaming current principle is not completely
understood, the Electrokinetic Charge Analyzer (ECA) can
provide valuable data for colloidal systems. The ECA’s
output is the STREAMING CURRENT VALUE (SCV), a term which
is commonly interchanged with “charge” or “charge
measurement.”...

As originally developed, the streaming potential measurement
utilized a capillary passage or porous plug of the material
of concern, through which the bulk fluid can be forced
by an applied pressure. Counter-ions in the diffuse layer
surrounding the material then migrate with the fluid,
creating an electrical potential or current, either of
which can be measured...
