Proper Care & Maintenance
To keep your Milwaukee C66 performing at its best:
- Rinse After Use: Always rinse the EC probe with distilled water after measurements to prevent salt and residue buildup.
- Calibrate Regularly: Perform regular one-point calibrations using EC calibration solutions to ensure consistent accuracy.
- Store Properly: Store the unit in a dry, cool place. Replace the probe cap after each use to protect the sensor.
- Replace the Electrode When Needed: If readings become unstable or calibration fails, it may be time to replace the electrode.
- Avoid Extreme Conditions: Keep the tester away from direct sunlight, excessive heat, and freezing temperatures.
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.
- 2.00 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
