The Milwaukee EC59 PRO Waterproof EC/TDS/Temperature Tester is designed for aquaculture, food, wine, laboratory, water treatment, and many other applications.
Keeping EC in your target range helps to achieve better results.
EC electrodes can develop nutrient buildup over time. To minimize buildup, always rinse the probe in fresh tap water after every use.
The Milwaukee PRO Conductivity Tester, like all conductivity meters, provides a measure of electrically charged ions in a solution and is an absolute measure of conductivity.
EC/TDS can be converted. Different scales include the 500 scale, 650 scale, and the 700 scale.
Your µS/cm reading can be approximately converted to other scales as shown in the examples below.
2.00 mS/cm = 2000 µS/cm = 1000 ppm on .50 factor scale
2.00 mS/cm = 2000 µS/cm = 1400 ppm on the 442 scale or .70 factor scale
