Temperature compensation : Automatic

DESIGN FEATURES

• Measure conductivity and TDS with automatic temperature compensation
• Ideal range for hydroponics and other growers (0.00 to 20.00 mS/cm)
• Units in mS/cm or ppt easily converted to ppm
• Factory calibrated with the ability to recalibrate if necessary
• Replaceable electrode
• Completely waterproof to IP65
• Approximately 100 hours of use (4 x 1.5V batteries included)

CARE AND USE

MAINTENANCE

EC electrodes can build up with nutrients over time. Always rinse the probe with fresh tap water after each use to minimize buildup.

CONVERT EC TO TDS

The Milwaukee EC60 PRO Conductivity Tester, like all conductivity meters, provides a measurement of electrically charged ions in a solution and is an absolute measure of conductivity.
In hydroponics, EC is often converted to TDS in parts per million (ppm). Different scales are the 500 scale, 650 scale and 700 scale. However, true PPM can only be determined through chemical analysis.

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

2.00 mS/cm = 2000 uS/cm = 1000 ppm on 0.50 factor scale
2.00 mS/cm = 2000 uS/cm = 1400 ppm on the 442 scale or 0.70 factor scale
