The answer is your meter's conversion factor and should be a number between 0.50 and 0.72. To improve accuracy, take EC and ppm readings from your res daily for about ten days. Average the conversion factors. The more data points that you use, the closer you will be to finding your tru...
Conversion electrical conductivity into TDS If your water analysis indicates the TDS and the electrical conductivity, then it should be possible to establish the following relation. + 500 ppm correspond to 1000 μS / cm or 1 EC This can be easily measured with a TDS meter. NPK meters that ...

EC meter display in uS/cm to convert to TDS -- If your TDS meter is calibrated using 1382 ppm or 6.44 ppt then the conversion is (uS/cm x .50 factor) = (TDS) ppmEC meter display in uS/cm to convert to TDS -- If your TDS meter is calibrated using 1500 ppm then the conversion...
Since the relative density of water is related to its dissolved solids content, each increase of 0.0001 relative density at 15.6°C is approximately equal to 110 ppm. Of course, the sample must be cooled down to 15.6°C or a correction chart used(supplied with the hydrometer) for proper ...
10 EC/TDS CALIBRATION Accessories needed: • Use HI 70031 (1413 µS/cm) EC calibration solution or HI 70032 (1382 ppm, or mg/L) TDS calibration solution. Note: The conversion between EC and TDS is made by a built-in circuit, hence it is requested to calibrate the meter only in ...
