EC/TDS Testers

Soil Test™ Direct Soil EC Tester - HI98331

Soil Test™ Direct Soil EC Tester - HI98331

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 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.

Ultra Pure Water (UPW) Tester (0.000-1.999 µS/cm) - HI98309

The HI98309 uses a conductometric measurement to determine the purity of water. The HI98309 Ultra Pure Water tester (UPW) enables users to check the purity of water, best suited for electronics and semiconductor industries. This tester is housed in durable casing that provides excellent protection against harsh industrial environments.

The HI98309 features an amperometric graphite electrode that provides better repeatability in measurements, since they do not oxidize. An amperometric measurement of EC is based on Ohm’s Law, I = V/R, where R depends on the distance between two pins and their surface. Oxidation changes both the distance and surface, which will affect accuracy. The non-oxidizing graphite pins are able to provide an optimal surface for accurate, dependable results. When calibration is needed, simply submerge the electrode tip into calibration solution and adjust the trimmer on the side of the tester.
