The C66 is a conductivity IP65 waterproof tester, specifically designed for the hydroponics and Agricultural markets, with automatic temperature compensation and 1 point manual calibration. The tester has a range of 0.00 to 10.00 mS/cm.
The C66 has a replaceable electrode and is supplied in a casing with calibration solution sachets (M10031) and screwdriver for calibration. The modular design allows easy electrode and battery replacement.
- Measures conductivity and temperature with automatic temperature compensation
- Ideal range for hydroponics (0.00 to 10.00 mS/cm)
- Units in mS/cm easily convertible to ppm
- Factory calibrated with the ability to recalibrate if needed
- Replaceable electrode
- Fully waterproof to IP65
- 250 hours continuous use (3 x 1.5V batteries included)
CARE AND USE
MAINTENANCE
EC electrodes can develop nutrient build up over time. To minimize 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.
2.00 mS/cm = 2000 uS/cm = 1000 ppm on .50 factor scale
2.00 mS/cm = 2000 uS/cm = 1400 ppm on the 442 scale or .70 factor scale
