Milwaukee EC40 Manual

CARE AND USE

MAINTENANCE

EC/TDS electrodes can develop nutrient build up over time. To minimize build up, always rinse the probe in fresh tap or DI water after every use.

CONVERTING EC TO TDS

The Milwaukee EC40 meter, 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, the EC40 has all the readings direct EC/TDS/CF.

Your uS/cm reading can be approximately converted to TDS (ppm) as shown in the examples below.

1 uS/cm = 0.5 ppm on a .5 factor scale
1 uS/cm = 0.7 ppm on a .70 factor scale (442)
