3P Instruments DT-700 electric conductivity of organic solvents and dispersions

Electric conductivity of organic solvents and dispersions

The 3P Instruments DT-700 measuring cell consists of two coaxial stainless steel electrodes and a guard electrode. The task of the latter is to eliminate leakage currents between the measuring electrodes. For easy cleaning after analysis, the outer hollow cylinder electrode can simply be pulled off.

During a measurement, the instrument applies a sinusoidal voltage to the outer electrode and measures the current that flows through the sample to the inner electrode. The frequency of this applied voltage is changed depending on the measured conductivity in the range from 1 to 10 Hz.

Features:

• For low polar (alcohols) down to non-polar solvents (toluene, hexane, etc.)
• Measurement of impurities or ionic content of polar and non-polar solvents, suspensions and emulsions
• Stand-alone device with small monitor and integrated computer
• Easy cleaning and calibration
