MOD-4100S On-line Salt in Crude Oil Analyzer

The MOD-4100S by Modcon Systems is designed to provide real-time analytical data of salt concentration in crude oils, based on ASTM D-3230 electrometric method — measuring conductivity when the sample is dissolved in a mixture of aromatic and alcoholic solvents.
