Care and Use
Maintenance
TDS/PPM electrodes can develop nutrient build up over time. To miminize build up, always rinse the probe in fresh tap or DI water after every use.
Converting TDS to EC
The Milwaukee TDS Pen, like all TDS meters, provides a measure of Total Dissolved Solids (ppm) reading, of contaminates per unit of volume in a solution.
TDS/PPM is often converted to µS/cm. Different scales include the 500 scale, 650 scale and the 700 scale.
Your TDS/PPM readings can be approximately converted to µS/cm as shown in the examples below.
1 ppm = 2 µS/cm on the 0.5 factor scale
1 ppm = 1.43 µS/cm on the 442 scale or .70 factor scale
Thank you for considering Milwaukee to help you take your results to the next level.
