Salts in Crude Analyzer


Koehler Instrument Company

Summary of Method

Salt content is determined by measuring the conductivity of a solution
of crude oil in a polar solvent when subjected to an alternating electrical
current and is obtained by comparison of the resulting conductance to a
calibration curve of known salt mixtures.



Utilizes the latest low-voltage, synchronous detection technology for conductivity measurements and a high-accuracy thermistor array to measure sample temperature. Automatically calculates salt concentration directly from acquired temperature and conductivity values. Measures conductivity over four ranges 0-2, 2-20, 20-200, and 200-1500 mS with automatic range selection.

Easy-to-read alpha-numeric display shows any four of the following parameters at one time as chosen by the operator: salts, conductance, conductance @ 25°C, pH, pH millivolts, temperature (°C or °F), internal and external battery voltages, date, time, logging ID, and ID increment value.
