Care and Use

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

Converting EC to TDS
The Milwaukee PRO Conductivity Tester, like all conductivity meters, provides a measure of electrically charged ions in a solution and is an absolute measure of conductivity.

EC/TDS can converted. Different scales include the 500 scale, 650 scale and the 700 scale. 

Your µS/cm reading can be approximately converted to other scales as shown in the examples below.

2.00 mS/cm = 2000 µS/cm = 1000 ppm on .50 factor scale

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