Milwaukee CD610 Digital High Range TDS Pen

Digital. Simple. Compact. The Milwaukee CD610 Digital High Range Total Dissolved Solids (TDS) Pen is designed for aquariums, pools and education and many other applications. The CD610 helps you make sure your fish tank water is clean and healthy. It is also a cost effective tool for teacher's science labs. Keeping ppm in your target range helps to achieve better results. Design Features Measures Total Dissolved Solids (TDS) direct (ppm). Ideal range for aquariums & pools (0 to 10000 ppm). Units in ppm easily convertible to µS/cm. Simple one-point calibration. Factory calibrated with the ability to recalibrate if needed. Use calibration solutions M10038B 6.44 ppt. Automatic Temp. Compensation (ATC) Battery life of approx. 300 hours of continuous use Care and Use Maintenance EC/PPM electrodes can develop nutrient build up over time. To miminize 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 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 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 Specifications for Milwaukee CD610 Digital High Range TDS Pen Range: 0 to 10000 ppm Resolution: 100 ppm Accuracy@20 °C (68 °F): ±2% full Scale Typical EMC Deviation: ±2% full Scale Calibration: Manual, at 1 point through trimmer Temperature Compensation: Automatic from 5 to 50°C (41 to 122 °F), with ß=2%/°C Environment: 0 to 50°C / 32 to 122°F; max RH 100% Battery Type: 4 x 1.5V Alkaline (included) Coin Cell Type: LR44 Battery Life: Approx. 300 hours of continuous use Calibration Solution: M10038B (25 sachets 20 mL ea.)
