Pocket size EC/TDS/Temp Meter from Milwaukee is perfect for measuring the EC or "electrical conductivity" of your nutrient mix.
These meters include features such as:
A replaceable probe,
Temperature in °C or °F,
Temperature compensation.
Battery indicator,
Stability indicator,
Auto shut off and calibration all in a floating, water proof casing.
Milwaukee EC60 shows on the dual level LCD the EC (20.00 mS/cm) or TDS (10.00 ppt) value. Also, it displays the temperature from 0.0 to 60.0°C (or 32.0 to 140.0°F) on the second level.
EC electrodes can get nutrient build up over time. To minimize build up, always rinse the probe in fresh tap or DI water after every use.
1 uS/cm = 0.5 ppm on a .5 factor scale 1 uS/cm = 0.7 ppm on a .70 factor scale (442)
