The Milwaukee C66 (High Range) Waterproof Conductivity (EC) Pens is designed for aquarium, aquaculture, agriculture, and pool applications.
or agriculture, C66 helps to make sure plants are receiving the right amount of nutrient. Keeping EC in your target range helps to achieve better results.
EC electrodes can develop nutrient build up over time. To minimize build up, always rinse the probe in fresh tap water after every use.
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.
2.00 mS/cm = 2000 uS/cm = 1000 ppm on .50 factor scale
2.00 mS/cm = 2000 uS/cm = 1400 ppm on the 442 scale or .70 factor scale
Thank you for considering Milwaukee to help you take your results to the next level.
