The HI98331 Soil Test™ is a pocket tester specifically designed to directly measure soil electrolytic conductivity (EC) and temperature for quick and accurate readings. With a compact size, single button operation, and automatic calibration, Soil Test is an excellent choice for taking direct conductivity measurements in soil eliminating the need to create soil slurries. 

  • Allows for direct measurement in soil
  • 4.5" Stainless Steel Penetration Electrode
  • Automatic Temperature Compensation

Features

Selectable units for conductivity measurements are μS/cm, mS/cm, or dS/m

One-point calibration to 1413 µS/cm conductivity standard

Uses a fixed 2%/oC temperature correction coefficient

Stainless steel penetration electrode

Waterproof casing

 

Understanding EC

Electrolytic conductivity (EC) is a measurement made in which electrical charges of particles in a medium are moved under the influence of a potential difference. EC is a measure of concentration, however, it is non-specic for ion type. An ion is a charged particle present in the solution that contributes to the current flow. Ions are formed when a salt such as sodium chloride is dissolved in water to form particles having electrical charges. Sodium chloride, separates into Na+ and Cl-

Electrical conductance, the ability of a substance to conduct an electrical current is the reciprocal of electrical resistance. “Conductance” and “Resistance” depend on the geometrical dimensions of the substance being measured. Conductivity and resistivity are “normalized” terms that are used to denote a bulk intrinsic property of a substance. This is the measurement a standardized EC probe on a Conductivity or resistivity meter provides. Conductivity measurements can be used to provide additional industry specific measurements; TDS, Salinity and USP compliant conductivity. Many of Hanna’s meters provide these measurements also.
