Conversion of reading from EC to TDS
The Milwaukee PRO Conductivity Tester, like all conductivity meters, measures electrically charged ions in solution and is an absolute measure of conductivity.
In hydroponics, EC is often converted to TDS in parts per million (ppm). The different scales include the 500 scale, the 650 scale and the 700 scale. However, the real PPM can only be determined by chemical analysis.
Readings in mS /cm can be approximately converted to TDS (ppm) as shown in the examples below.
2.00 mS /cm = 2000 uS /cm = 1000 ppm on the 0.50 ratio scale
2.00 mS /cm = 2000 uS /cm = 1400 ppm on the scale 442 or the factor scale 0.70
