The Milwaukee CD601 Digital Electrical Conductivity (EC) Pen is designed for aquariums, aquaculture, pools, water treatment and many other applications. With the CD601 you can ensure that your water contains the right amount of nutrients to ensure aquarium health.
EC tester in laboratory quality for professional and hobby applications.
Measures microSiemens (US / cm) directly and with automatic temperature compensation.
Ideal range for aquariums (0 to 1990 uS / cm).
Factory calibrated with the ability to recalibrate if needed.
Automatic Temperature Compensation (ATC)
Approx. 350 hours of continuous operation (4 x 1.5V batteries included).
Easy single point calibration.
Like all conductivity meters, the Milwaukee EC Pen provides a measure of electrically charged ions in a solution and is an absolute measure of conductivity.
EC is often converted to ppm (parts per million) into TDS. Various scales include the 500 scale, the 650 scale and the 700 scale. However, real PPM can only be determined by chemical analysis.
Your mS/cm value can be converted approximately to TDS (ppm) as shown in the following examples.
2,000 µS / cm = 2.0 mS / cm = 1000 ppm on the 50-factor scale.
2,000 µS / cm = 2.0 mS / cm = 1400 ppm on the 442 scale or the 0.70 factor scale
