Conductivity Calibration

Bante530 portable conductivity/TDS meter is capable of using the three types of conductivity electrodes. Before calibration or measurement, you need to

select the different sensors as per your sample concentration. The table below shows available sensors and its effective measuring ranges.

Make sure that you selected the cell constant between 0.1, 1 or 10 in the setup menu. If the current option is “USER”, the automatic calibration function

will be disabled (Refer to Setup Menu section).

In the automatic calibration mode, the meter allows up to 5 points calibration. To ensure higher accuracy, we recommend that you perform 3 points

calibration or select a standard value close to the sample value you are measuring. The meter will automatically detect these conductivity standard solutions

and prompt the user to calibrate the meter. When the calibration is completed, all new calibration values will automatically override existing data.

The following table shows acceptable conductivity range of calibration solution for each measuring range.
