Hanna Soil Test™ Direct Soil EC Tester - HI98331

Hanna Soil Test™ Direct Soil EC Tester - HI98331

The HI98331 Soil Test™ is a pocket tester specifically designed to directly measure soil 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 elimintating the need to create soil slurries. 

• Waterproof
• 4.5" Stainless Steel Penetration Electrode
• Automatic Temperature Compensation

The HI98331 features a stainless steel penetration electrode that provides the ability to take direct measurements in soil. When calibration is needed, simply submerge the electrode tip into calibration solution and and enter calibration mode for automatic 1 point calibration.

Electrolytic conductivity, abbreviated as 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 because the greater the cross-sectional area, the greater the current that can flow.
