results. Saturated Media Extract (SME) analysis has been shown to eliminate these
problems. The samples should not be fired, sieved or pulverized as this will affect the
growth medium properties and alter the results. Traditionally, the soil solution from the
saturated medium is extracted by a vacuum pump. However, the Field Scout Soil &
Water EC Meter allows the saturated sample to be tested directly.
Procedure
• Moisten the media sample with distilled water to reach a consistent “saturated”
moisture level. When saturated, the media should glisten and slide from the
mixing spatula with little or no free water.
• Wait 15 minutes and add more water if needed. The sample should have the
consistency of a paste with slightly more water than if the media was in a pot and
fully irrigated.
• Press On/Off button to power up the meter.
• Insert the probe tip into the media and read the results.

Liquid Measurement/Other Functions
Water (Liquid) Measurements
The Field Scout Soil & Water EC Meter can also measure the EC of liquids. Simply dip
the electrode tip into the solution and wait for the reading to stabilize (a stable reading
occurs when the readout has not changed for 3 seconds).
Converting Meter Readings to PPM
To convert ms/cm to Parts per Million (PPM) simply take the meter reading and multiply
it by 640. Example 2.75 mc/cm X 640 = 1760 ppm
Other Functions
Hold
Pressing the HOLD key will freeze the display. Press HOLD again to release.
Temperature Measurement
If the temperature of the sample is desired, press the MODE key to toggle between
displaying temperature (C) and conductivity on the LCD.
