Easy to Use and Carry!

Works Great. I would buy again!

CARE AND USE

Milwaukee CD611 MAINTENANCE

EC electrodes can develop nutrient build up over time. To miminize build up, always rinse the probe in fresh tap 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
