Milwaukee CD601 Digital Conductivity Pen (EC)
The Milwaukee CD601 Digital Electrical Conductivity (EC) Pen is designed for aquariums, aquaculture, pools, water conditioning and many other applications. The CD601 helps make sure that water has the right amount of nutrients to help keep fish tanks healthy. It also helps to keep filters up-to-date and clean for water filtration.

CARE AND USE
MAINTENANCE
EC electrodes can develop nutrient buildup over time. To minimize buildup, always rinse the probe in fresh tap or DI water after every use.
CONVERTING EC TO TDS
The Milwaukee EC Pen, like all conductivity meters, provides a measure of electrically charged ions in a solution and is an absolute measure of conductivity.
EC is often converted to TDS in parts per million (ppm). Different scales include the 500 scale, 650 scale and the 700 scale. However, true PPM can only be determined through chemical analysis.
Your mS/cm reading can be approximately converted to TDS (ppm) as shown in the examples below.
2,000 µS/cm = 2.0 mS/cm = 1000 ppm on .50 factor scale
2,000 µS/cm = 2.0 mS/cm = 1400 ppm on the 442 scale or .70 factor scale
