Milwaukee CD600 Digital Total Dissolved Solids Pen (TDS)
The Milwaukee CD600 Total Dissolved Solids (TDS) Pen is designed for hydroponics, aquariums, horticulture, water conditioning and many other applications. The CD600 helps to make sure that plants are receiving the right amount of nutrients. It also helps to keep filters up-to-date and clean for water filtration.
CARE AND USE
TDS/PPM 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 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 uS/cm. Different scales include the 500 scale, 650 scale and the 700 scale.
Your TDS/PPM readings can be approximately converted to uS/cm as shown in the examples below.
1 ppm = 2 uS/cm on the 0.5 factor scale
1 ppm = 1.43 µS/cm on the 442 scale or .70 factor scale
