SKU: HI98331 Category:


The HI98331 Direct Soil EC Tester/Pen is a pocket tester that allows you to directly measure soil conductivity (EC) and temperature. The Direct Soil EC Tester/Pen is a great option for taking direct conductivity measurements in soil because of its compact size, automatic calibration, and single button operation.

The HI98331’s steel penetration electrode means you no longer have to make soil slurries. The HI98331 has an integrated temperature sensor that is used so that EC measurements are automatically temperature compensated.This creates readings that are much more accurate. This EC tester is great for environmental and agricultural testing.

The Hanna GroLine Direct Soil EC Tester/Pen lets you measure the bulk EC of your soil with a soil conductivity test. Bulk electrical conductivity of soil conveys the total conductivity. Total conductivity includes the EC of the soil, air, and moisture in your sample. All these things carry charged ions that would read as EC. This reading is very useful; you can calculate your pore water conductivity and saturated extract conductivity from the result. You would need to know your water content (how much water there is in your soil) to perform that calculation. How To Measure the Bulk EC with your Direct Soil EC Meter:

  • Pick your testing location.
  • Rinse the testing probe with deionized water, and make sure it is dry.
  • Check the soil and ensure that the soil is moist.
  • Use a ruler or auger to make a hole in the soil. This keeps the testing depth consistent.
  • Insert your soil conductivity tester directly into the soil, and take your measurement.
