HI 3820

Acidity can be caused by mineral or organic acids, or by carbon dioxide as carbonic acid. Acidity of aqueous solutions contributes to corrosiveness and influences the rate of biological processes. For these reasons acidity is monitored in fish farming, soil testing, environmental testing, treated waste water discharge, lakes and rivers. The Total Exchangeable Acidity (TEA) measures the total amount of soil acidifiers (hydrogen, aluminum, iron and manganese) in meq/100g unit, equivalent to 1000 parts per 100g of soil. A high value of total exchangeable acidity means a low soil pH level. Soil with high acidity can damage some crops.


HI 3811

This parameter is important in determining the corrosive properties of minerals found in water, such as, silicates, carbonates, bicarbonates, and dissolved salts of phosphates and some organic acids. Testing alkalinity is important in the treatment of drinking water, wastewater, pools, heating and cooling, food and beverage cleaning systems, soil and environmental testing, as well as in agriculture, and aquaculture applications.


HI 3824

Concentrations of ammonia in rivers and drinking water reservoirs indicate the presence of agriculture or urban pollution. When the concentration of ammonia is high enough, it can alter the smell and taste of water. In industrial applications, high concentrations of ammonia can cause corrosion in pipes. Ammonia is also monitored in aquariums and fish farming applications because of its toxicity to fish. HANNA®' kits allow you to test ammonia in fresh and salt water using the Nessler method.


HI 3818

In nature, lakes and rivers contain carbon dioxide in concentrations smaller than 10 mg/L (or ppm), however, stagnant or contaminated water can contain higher concentrations because of organic decomposition. This creates a problem for fish farming applications. Carbon dioxide is added to drinking water during the final phases of the purification process. In water softening processes carbon dioxide must be kept at a certain level in order to prevent corrosion.


HI 3815           

Chloride is one of the most common ions present in water. In drinking water, its level must be kept low because it can adversely alter the taste. In other applications, chloride levels must be monitored to prevent scaling and corrosion. In high concentrations, chloride can even corrode stainless steel and is detrimental to vegetation. HANNA® presents a new test kit for chloride analysis. HI 3898 allows the user to determine high concentrations of chloride in wastewater, which can interfere with official COD analysis methods. This test, according to the ISO 15705:2002 method, indicates chloride interference in seconds. The chloride concentration is considered too high if greater than 1000 ppm (for COD test according to ISO directives) or higher than 2000 ppm (for COD test according to the USEPA, APHA, AWWA and WEF methods). If a high concentration of chloride is found, the sample must be diluted.


HI 3831F

Chlorine is the most commonly used water disinfectant in applications that vary from treatment of drinking water and wastewater, pools and spas sanitization, to food processing and sterilization. Chlorine present in water binds with bacteria, leaving only part of the original quantity (free chlorine) to continue its disinfecting action. If the free chlorine level is improper with respect to the pH, water will have an unpleasant taste and odor and the disinfecting potential of the chlorine will be diminished.

Free chlorine reacts with ammonium ions and organic compounds to form chlorine compounds with diminished disinfecting capabilities compared with free chlorine. Combined chlorine and free chlorine together result in total chlorine content.


HI 3831T

Chlorine is the most commonly used water disinfectant in applications that vary from treatment of drinking water and wastewater, pools and spas sanitization, to food processing and sterilization. Chlorine present in water binds with bacteria, leaving only part of the original quantity (free chlorine) to continue its disinfecting action. If the free chlorine level is improper with respect to the pH, water will have an unpleasant taste and odor and the disinfecting potential of the chlorine will be diminished.

Free chlorine reacts with ammonium ions and organic compounds to form chlorine compounds with diminished disinfecting capabilities compared with free chlorine. Combined chlorine and free chlorine together result in total chlorine content.


HI 3812

Hardness in water is mainly due to the presence of Calcium and Magnesium ions and each contributes to the amount of total hardness. Monitoring and controlling hardness is instrumental in order to prevent scaling and corrosion.

Water is categorized as very soft (0-70 mg/L), soft (70-150 mg/L), slightly hard (150-250 mg/L), moderately hard (250-320 mg/L), hard (320-420 mg/L) and very hard (420 mg/L and above), according to the hardness scale. HANNA®' kits cover all of these ranges.

HANNA® offers the HI 3840-S, HI 3841-S and HI 3842-S chemical test kits packed in sachets offering a low cost alternative.


HI 3839

Hydroxide ions found in natural waters may indicate artificial contamination. Hydroxide ions may also be a measure of the corrosiveness of water on materials subject to attack by basic media. In copper electrolysis plating, hydroxide ions react with formaldehyde to reduce copper.


HI 3832

Iodine is used as an alternative to chlorine and bromine in drinking water and swimming pools. Pool water treated with iodine does not irritate the human eye.


HI 3834

Iron concentration in natural water is typically below 1 mg/L (ppm), but the level can be much higher due to industrial discharges. Water containing iron is not dangerous to health, but it has a strong taste and can stain.

HANNA®' test kits allows you to determine the total concentration of iron as both Fe²+ and Fe³+ ionic status.


HI 3835

Salinity is a measure of the concentration of total dissolved salts in a body of water.

Salinity is ecologically important in that it influences the type of organism that can live in the water. The optimal concentration of salinity varies from species to species. It is crucial to the health of a system that this parameter is monitored. Applications are found in an variety of fields from water in fish farming and aquariums as well as food processing and cheese production. Salinity is expressed in g/kg or ppt (parts per thousand), as well as Practical Salinity Units (psu).


HI 38001

Sulfate is widely present in natural waters. It is not toxic but has to be kept below a certain threshold because it imparts an unpleasant taste to the water.

The concentrations are particularly higher close to mine run-off water. Sulfate is also widely used as a nutrient in agriculture. The HANNA instrument kit covers an extensive range for measuring sulfate concentrations.


HI 3874

Nitrate is an essential nutrient for plants but must be monitored in order to maintain proper health and optimum yield. Excessive levels are detrimental and can even be toxic, effectively "burning" the plants. Nitrate can be found in natural surface water, as well as in underground water. In drinking water, the nitrate level must be monitored because of its toxic nature. Domestic water supplies should not contain nitrate in excess of 45 mg/L.

HI 93719

Water, with exception to distilled water, contains dissolved salts (magnesium and calcium carbonates). The concentration of these salts determines the water hardness, which can be expressed in calcium carbonate or magnesium carbonate. The sum of these two represents the total hardness level.

The presence of dissolved salts is due to the fact that water often comes from underground sources which are in turn made up of rain water filtered through deep ground layers. Rain water eventually reaches a waterproof flooring and forms a natural tank which is also called the water bearing stratum.

By passing through the various layers of soil and rock, rain water dissolves some of the mineral substances. Hardness is a consequence of the type of rock layers which the water passes through and of its permanence in the water bearing stratum.

In addition, this parameter is also related to the phenomenon of pipe rusting in water heating and cooling systems, reverse osmosis and demineralization plants.

HANNA® offers two different meters to measure magnesium and calcium, results are expressed in CaCO³ equivalent.
