Comparison of TDS-meters (Mi Xiaomi TDS Pen and TDS-3).
Comparison of the accuracy of the readings of these devices with a calibration solution is made. It is also shown that the use of distilled water for calibration is erroneous (because it is a very rough calibration).
It is justified why this particular calibration solution is used, and not another!
For reference.
To convert EC (μS / cm) to TDS (ppm), the conversion factor (factor) is used. Depending on the calibration used at the plant (NaCl solution, 442 (mixture of salts) or KCl), the conversion factor can be from 0.47 to 0.85. The coefficients that are most often used for conversion are indicated in the video.
