CD611 Conductivity Tester with ATC and 1 point manual calibration by Milwaukee

The Milwaukee Conductivity Pen is designed for hydroponic and other growers to help you make sure that your plants are receiving the right amount of nutrient. Keep EC in your target range to help your achieve better results.

DESIGN FEATURES

• Measures conductivity and temperature with automatic temperature compensation
• Ideal range for hydroponics (0 to 20,000 μS/cm)
• Units in μS/cm easily convertable to ppm
• Factory calibrated with the ability to recalibrate if needed
• 350 hours continuous use (3 x 1.5V batteries included)

MAINTENANCE

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

CONVERTING EC TO TDS

The Milwaukee EC Pen, like all conductivity meters, provides a measure of electrically charged ions in a solution and is an absolute measure of conductivity.

EC is often converted to TDS in parts per million (ppm). Different scales include the 500 scale, 650 scale and the 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.

2,000 μS/cm = 2.0 mS/cm = 1000 ppm on .50 factor scale

2,000 μS/cm = 2.0 mS/cm = 1400 ppm on the 442 scale or .70 factor scale
