Description

Milwaukee EC40 EC/TDS Nutrient Meter

The Milwaukee EC40 EC/TDS Nutrient Meter is designed for hydroponics, horticulture and agriculture.  It helps make sure that vegetables and plants are receiving the right amount of nutrients to promote healthy growth with low to zero product waste.

Features:

  • Measures conductivity (EC) and total dissolved solids (TDS) with automatic temperature compensation
  • Ideal range for Hydroponics (0.2 to 4 mS/cm | 2 to 40 CF | 140 to 2800 ppm 0.7 scale | 100 to 2000 ppm 0.5 scale)
  • Units directly in mS/cm/CF/PPM (no conversions required)
  • Factory calibrated; no continuous calibration required
  • High accuracy
  • Automatic Temperature Compensation (ATC)
  • Auto on/off feature
  • Blue LED display
  • Graphite electrode in ABC + PC body
  • Battery level indicators
  • Battery life up to 3 years with approx. 10 measurements per day
  • 3 X 1.5V AA (batteries included)

CARE AND USE

MAINTENANCE

EC/TDS 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 EC TO TDS

The Milwaukee EC40 meter, 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, the EC40 has all the readings direct EC/TDS/CF.  

Your uS/cm reading can be approximately converted to TDS (ppm) as shown in the examples below.

1 uS/cm = 0.5 ppm on a .5 factor scale 
1 uS/cm = 0.7 ppm on a .70 factor scale (442)
