SALTS IN CRUDE OIL, ELECTROMETRIC METHOD
ASTM D 3230
This test method is based on the conductivity of a solution of crude oil in a polar solvent when subjected to an alternating electrical stress.
The sample is dissolved in a mixed solvent and placed in a test cell consisting of a beaker and two parallel stainless steel plates.
An alternating voltage is impressed on the plates and the resulting current flow is shown on a milli-ammeter. The salt content is obtained by reference to a calibration curve of current versus salt content of known mixtures.
C.E. labelled tester for determination of salts in crude oil including digital display of both current and voltage, easily and continuously adjustable.
Adjustable current between 0 and 300 VAC, very easy to operate fully according to the standard
