High Sensitivity Of Conductivity Detectors


The conductivity detector has many features, including a convertible probe, temperature °c or °f, adjustable automatic temperature compensation, battery indicator, stability indicator, automatic shutdown and automatic calibration at float, waterproof enclosure. EC59 also displays the EC (3999ΜS/CM) or TDs ($number ppm) value on the screen. He can also display the temperature at the bottom at the same time from 0.0-60.0 °c (or 32.0-140.0 °f). EC60 also displays the value of the EC ($number ms/cm) or TDS ($number ppt) on the screen, Conductivity Detector and he can also display temperatures at the bottom from 0.0-60.0 °c (or 32.0-140.0 °f).

The conductivity detector has reliable quality, can quickly and accurately measure the conductivity and total solid dissolved quantity, does not need the colorimetric or uses the titration bottle, simply inserts the test pen into the measured sample to be able to read the numerical value. Can be automatically 0-50 ℃ temperature compensation, temperature compensation coefficient set to 2% to ensure accurate measurement data. Conductivity Detector The correction is quick and simple, just insert the electrode into the correction fluid and adjust the correction knob.

Conductivity detector consists of conductivity pool, electronic circuit, transform sensitivity device and digital display device, and the conductivity pool is the core part.

The basic structure of the conductivity pool is to place two electrodes in the chromatographic column outflow liquid, then measure the conductivity of the solution through the electronic circuit, Conductivity Detector and the detection volume can reach the micro-rise or the upgrade.

Conductivity Detector Features:

1, the sensitivity is high, the detection lower limit generally is the Gram class, Conductivity Detector sometimes may reach the leather gram class.

2, good selectivity, can determine a large number of non electrical active substances in the polar trace of electrical active substances.

3. Wide linear range.

4, simple structure, easy to operate automatically

Conductivity Detector Working principle:

When the voltage is applied to the two electrodes of the conductivity pool, the anions in the solution move in the sun and the cations move toward the cathode. The number of ions in the electrolyte solution and the moving rate of the ions determine the resistance of the solution, Conductivity Detector and the rate of ion movement depends on the ionic charge and its size, medium type, solution temperature and ionic concentration. The voltage applied can be either a DC voltage or a sine or square wave voltage. When the applied voltage is determined, the current value in the circuit can be measured, that is, the conductance value can be measured.
