MAINTENANCE
Over time, EC electrodes can accumulate nutrients. To minimize buildup, always rinse the probe with fresh tap water after each use.
CONVERSION OF EC READING TO TDS
Like all conductivity meters, the Milwaukee PRO conductivity tester provides a measurement of 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). Different scales include the 500 scale, the 650 scale and the 700 scale. However, the true 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 a 0.50 coefficient scale
2.00 mS/cm = 2000 uS/cm = 1400 ppm on a 442 scale or 0.70 coefficient scale
