Product information “HI 98331 Direct Soil EC and Temperature Meter with Built-in Stainless Steel EC Probe”
The Soil Test? Direct Soil EC Tester – HI98331 is a rugged and reliable pocket-sized tester that offers quick and accurate readings. The Soil Test? Direct Soil EC Tester – HI98331 features a stainless steel penetration probe for direct measurement of conductivity in soils. With a compact size, single button operation, and automatic calibration, Soil Test is an excellent choice for taking direct conductivity measurements in soil.
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 1point calibration.
Electrolytic conductivity, abbreviated as EC, is a measurement made in which electrical charges of particles in a medium are moved under the in?fluence of a potential diff?erence. EC is a measure of concentration, however, it is non-speci?c 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-. This is a simplifi?ed de?nfinition for the measurement is a?ffected by many things such as the type of ionic compound(s) dissolved in the water; the ions mobility, the solution viscosity, temperature as well as concentration.
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 specifi?c measurements; TDS, Salinity and USP compliant conductivity. Many of Hanna?s meters provide these measurements also.
