Hanna GroLine Soil Test Direct Soil EC Tester - HI98331

Hanna GroLine Soil Test Direct Soil EC Tester - HI98331

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 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-specific for ion type. An ion is a charged particle present in the solution that contributes to the current Šflow. 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 “normalised” terms that are used to denote a bulk intrinsic property of a substance. This is the measurement a standardised 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.

Attention Valued Customer:

Ph testers and Ph probes are sensitive scientific equipment. They will require extra care and maintenance from the user (you) to ensure accurate readings, measurements and valid warranties.

Ph testers (without replaceable probes) and Ph probes are electrical sensors and considered a consumable item. You should aim to be replacing these over time as you do media, nutrients, etc. Probes and Pens (without replaceable probes) only have a 6-month warranty from date of purchase and will not be honoured without receipt of purchase.

Probes and Pens with proper care can last for years, but as it is a live charge in the electrode it can be finished from 6 months. More so, if correct care procedures have not been maintained. Hydroponic nutrients in particular degrade Ph probes much faster than other disciplines.

Probes must always be re-hydrated before use in storage solution, available for purchase in store

Probes must be kept in storage solution when not in use (in tank monitors excepted)

IF IT DRIES….IT DIES

Please read the entire contents of the booklets and handouts that come with all Ph instruments carefully.
