Maintenance

EC electrodes can develop nutrient build up over time. Always rinse the probe in fresh tap water after each use to reduce buildup.

Converting EC to TDS

The Milwaukee EC Pen, like all conductivity metres, 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. Nonetheless, 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.
