Overview

In many industrial fields, it is necessary to measure the conductivity value of the same sample solution to intuitively understand its total ion concentration. Conductivity value is a simple, fast, and inexpensive method for measuring the ion concentration of a solution, but its disadvantage is that it cannot measure the concentration of a specific ion. The Ohhaus four ring conductive electrode STCON3 eliminates the polarization error caused by ordinary two ring conductive electrodes and has a wider measurement range. Within the appropriate measurement range, an accuracy of 0.5% can be achieved. When it is less than 70 μ s/cm, the measurement accuracy error increases and it is not recommended to use it. Welcome to inquire in detail.

STCON3Conductivity Electrode Operation Guide

During the measurement process, the plastic sleeve must be tightly fitted onto the electrode main rod.

2. The liquid level during measurement must not be lower than the scale line on the electrode sleeve.

3. During the transition from high conductivity measurement to low conductivity measurement, special attention should be paid to cleaning the electrodes to prevent measurement deviation.

4. Pay attention to observation and ensure that there are no bubbles in the measuring pool. It is recommended to insert the electrode into the solution at a certain angle and then vertically to avoid the occurrence of bubbles.

When measuring at different temperatures, it is necessary to wait for the instrument to stabilize the sample temperature display before proceeding. In this case, it is recommended to use manual endpoint judgment.

Samples below 6.70 µ S/cm are not recommended to use this electrode.

During and after the measurement process, clean the electrodes with distilled water.

8. For calibration and measurement steps, refer to the corresponding conductivity meter manual.

Ohhaus conductivity electrode STCON3Precautions

Do not remove the sleeve during the measurement process.

2. This electrode should not be used for measuring organic solvents, nor should it be cleaned with organic solvents.

3. It should not be used in environments beyond the temperature range of 0-50 ° C.

4. The measurement performance of the electrode can only be ensured when used together with the accompanying conductivity meter.

Recommended instruments: Ohhaus conductivity meter ST300C, Ohhaus ST3100C conductivity meter, etc. For more water quality testing instruments, please feel free to inquire with sales personnel.
