Complete setup
Water hardness has traditionally been defined as the capacity of water to precipitate soap. The ionic species in the water causing the precipitation was later found to be primarily calcium and magnesium. Thus, water hardness is actually a quantitative measure of these ions in the water. It is also now known that certain other ion species, such as iron, zinc, and manganese contribute to the overall water hardness. The measure and subsequent control of water hardness is essential to prevent scaling and clogging in water pipes.
Complete setup
- All required materials are included with the test kit, such as the sample beaker, plastic pipette, and reagent dropper bottles.
- Readings from 0.0 to 30.0 mg/L are determined to 0.3 mg/L resolution.
- Readings from 0 to 300 mg/L are determined to 3 mg/L resolution.
- There is no need to buy a new kit when reagents are exhausted. The HI3812-100 can be ordered to replace the reagents supplied with the kit.

The HI98120 is a waterproof ORP and temperature handheld meter. The housing of this tester is completely sealed to protect against the intrusion of water and is also designed to float if accidentally dropped into a body of water. The HI73120 replaceable ORP electrode is a cartridge design with the stainless steel round connector. With this type of design there are no pins that can bend or break during replacement. The ORP electrode also hase has an extendable cloth junction. This type of junction allows for the renewal of the junction by simply pulling out 3 mm (1/8") to clear any clogging which improves measurement response time and stability. The exposed stainless steel temperature probe on this meter facilitates a faster, accurate temperature measurement.
Similar to a pH measurement that quantifies the how acidic or alkaline solutions are, ORP (Oxidation Reduction Potential) measurements quantify the overall state of a solution as having the ability to oxidize or reduce a chemical species. Oxidizing and reducing reagents are used to participate in chemical reactions known as a redox reaction.
An important part of the ORP probe is to have a sensor that is chemically inert; meaning it cannot be oxidized or reduced itself. It must also have the proper surface characteristics to promote rapid electron exchange, a property known as high exchange current density. Two noble metals have proven to work well for this purpose: pure platinum and pure gold. Both are commonly used in the construction of ORP probes.
The platinum sensor is often preferred because it is mechanically simpler to produce. Platinum can be welded to glass and also has a similiar thermal expansion coefficient. Sensors made of gold cannot be welded to the glass and are often placed in plastic supports applied to the glass or plastic tube by means of tiny elastomeric bungs.
Many industries rely upon ORP measurements including swimming pools, food processing, boilers and cooling towers, and plating. The measurement of ORP helps the user monitor the effectiveness of disinfecting compounds including chlorine and ozone. ORP is also used to monitor redox reactions including the use of bisulfite in the reduction of hexavalent chromium to trivalent chromium in plating wastewater.

The HI98308 Pure Water tester is a rugged and reliable pocket-sized tester that offers quick and accurate readings. The HI98308 Pure Water tester features graphite electrodes to reduce polarization effects and an exposed temperature probe for fast response when compensating for temperature changes. Manual calibration is performed to a single point.
The HI98308 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.
The HI98308 uses a conductometric measurement to determine the purity of water. The HI98308 Pure Water Test (PWT) enables users to check the purity of distilled or demineralized water in laboratory or industrial environments. PWT is suited for fields such as printed circuit board washing, laundry, steam cleaning, checking car battery water and all areas where distilled, demineralized or pure water is used. This tester is housed in durable casing that provides excellent protection against harsh industrial environments.
Electrolytic conductivity, abbreviated as EC, is a measurement made in which electrical charges on atomic or larger sized 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 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 simplified definition as the measurement is affected 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 specific measurements; TDS, Salinity and USP compliant conductivity. Many of Hanna's meters provide these measurements also.

One-point calibration
The HI98308 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.
The HI98308 uses a conductometric measurement to determine the purity of water. The HI98308 Pure Water Test (PWT) enables users to check the purity of distilled or demineralized water in laboratory or industrial environments. PWT is suited for fields such as printed circuit board washing, laundry, steam cleaning, checking car battery water and all areas where distilled, demineralized or pure water is used. This tester is housed in durable casing that provides excellent protection against harsh industrial environments.
Electrolytic conductivity, abbreviated as EC, is a measurement made in which electrical charges on atomic or larger sized 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 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 simplified definition as the measurement is affected 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.
