Milwaukee EC60 PRO 3-in-1 Waterproof EC/TDS/Temp Tester with Replaceable Probe

Designed for hydroponic growers, the Milwaukee EC60 PRO Waterproof EC/TDS/Temperature Tester helps to make sure that your plants have the ideal amount of nutrient available. Keeping EC in your target range helps to achieve better results. Design Features Measures conductivity and TDS with Automatic Temp. Compensation (ATC) EC60 features the ideal high range EC measurement for aquaculture and other applications EC60 features the ideal high range EC Measurement for hydroponic and other growers Units easily convertible to other ranges Factory calibrated with the ability to recalibrate if needed Use MA9060 or M10030B 12,880 µS/cm Replaceable electrode Mi59P Fully waterproof to IP65 Approx. 100 hours of continuous use (batteries included) Care and Use 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 EC60 PRO Conductivity Tester, like all conductivity meters, provides a measure 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 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. 2.00 mS/cm = 2000 µS/cm = 1000 ppm on .50 factor scale 2.00 mS/cm = 2000 µS/cm = 1400 ppm on the 442 scale or .70 factor scale Specifications for Milwaukee EC60 PRO EC Range: 0.00-20.00 mS/cm TDS Range: 0.00-10.00 ppt Temp Range: 0.0 to 60.0°C / 32.0 to 140.0°F EC Resolution: 0.01 mS/cm TDS Resolution: 0.01 ppt Temp Resolution: 0.1°C / 0.1°F Typical EMC Temperature Deviation: ±0.3 °C (±0.6 °F) EC Accuracy: 2% Full Scale TDS Accuracy: 2% Full Scale Temp Accuracy: ±0.5°C / ±1°F Temperature Coefficient: Selectable TDS Conversion Factor: Selectable (default 0.5) Calibration: Automatic, 1 point Temperature Compensation: Automatic, with β=0.0 to 2.4%/°C Probe: Mi59P (replaceable) Environment: 0 to 50°C / 32 to 122°F; max RH 100% Battery Type: 4 x 1.5V; IEC LR44, A76 (included) Battery Life: Approx. 100 hours of continuous use Auto-off: After 8 minutes on non-use Dimensions: 7.9 inches - 1.5 inches (diameter) Weight: 3.5 ounces (99.22 g)
