Maintenance: EC electrodes can develop nutrient build-up over time. To minimise build-up, always rinse the probe in fresh tap water after each use!.

EC to TDS conversion: Milwaukee EC Pen, like all conductivity meters, measures electrically charged ions in a solution and provides 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 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.

1. 2.00 mS/cm = 2000 µS/cm = 1000 ppm on the .50 factor scale
2. 2.00 mS/cm = 2000 µS/cm = 1400 ppm on the 442 scale or .70 factor scale
