4. Pressing either calibration key will put the meter into CALIBRATION mode.
Press the Increase (INC) or Decrease (DEC) key to adjust the reading. If a key is
held down, the adjustment will happen more rapidly.
5. When the EC of the calibration standard is reached, release the keys for 3
seconds. The display will flash 3 times, and then show “ENT”. The Waterproof
EC Tester accepts the calibration value and returns to MEASUREMENT mode.
Important - The meter will NOT calibrate to the common 1314 US/cm (1.31 mS/cm)
conductivity standard.
Direct Soil EC Readings
Golf Course Greens/Sports Turf
For golf course greens and athletic fields, following irrigation or deep-soaking rain event
the stainless steel probe of the EC Meter can be inserted directly into the soil. By taking
measurements at different soil depths, you can determine where the salts are concentrated
in the soil profile. Soil moisture content will significantly influence the measured EC
value. To ensure accurate measurements, it is recommended the readings be taken when
soil moisture is close to field capacity by taking measurements approximately 30 to 60
minutes after irrigation. This should ensure the soil moisture level has approximately
reached field capacity. Or use the Turf-Tec Moisture Sensor and record soil moisture
readings along with EC Readings.
Probe to the depth of the turf root zone. Measurements exceeding 0.7 mS/cm
(approximately equivalent to 2.7 mS/cm in a saturated paste extract) will result in cool
season turf grass stress.
Procedure
1. Be sure soil is at field capacity or record moisture content reading from the Turf-
Tec Moisture Sensor in percent of soil moisture.
2. Press On/Off to power up the meter.
3. Insert Stainless steel probe tip into the soil to the desired depth.
4. Hold probe still as possible.
5. Wait for reading to stabilize (Stable 3 seconds)
6. Repeat for each one inch increment.
SME Measurement
Saturated Media Extract (SME) Measurements
Growth media used in most greenhouse operations is high in organic material and
processed materials and low in mineral soil. These materials are easier to handle, are
well aerated and have good moisture-holding properties, but have limited ability to retain
nutrients. Therefore, tests developed for field soils do not always yield meaningful
