Digital. Simple. Compact.

The Milwaukee CD610 Total Dissolved Solids High Range (PPM) Pen is designed for aquariums, pools, education, and many other applications. The CD610 helps make sure that you keep your fish tank water clean and healthy. It is a cost-effective tool for teachers' science labs. Keep PPM in your target range to help you achieve better results.

Design Features

• Measures Total Dissolved Solids (PPM) direct and with automatic temperature compensation.
• Ideal range for aquariums and pools (0 to 10000 ppm).
• Units in ppm easily convertible to uS/cm.
• Factory calibrated with the ability to recalibrate if needed.
• Automatic Temperature Compensation (ATC).
• 350 hours continuous use (4 x 1.5V batteries included).
• Simple one-point calibration.

Maintenance

EC/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/PPM Pen, like all TDS meters, provides a reading measured in parts per million contaminants per unit of volume in a solution.

TDS/PPM is often converted to uS/cm. Different scales include the 500 scales, 650 scales the 700 scales.

Your TDS/PPM reading 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
