Drop Count Titration A low-cost, portable titration method, drop counting is done using standardized titrants in special dropper bottles with calibrated droppers. To titrate, add an indicator to the sample, then add titrant dropwise until the color changes. Accuracy is within ± 5 %. Results are proportional to the number of drops used. Titrimetric Hach s Digital Titrator is a unique concept in titrimetric analysis. A precision dispensing device fitted with concentrated titrants in compact interchangeable cartridges, the Digital Titrator guarantees repeatability from test to test, and consistency from person to person. Prepared titrant solutions eliminate the time and labor involved in preparation of reagents and clean-up of burets and glassware. Equally suited for both laboratory and field analysis, the unbreakable Digital Titrator comes with a sturdy carrying case and a complete instruction manual. Colorimetric With this method you add one or more reagents to the sample to produce a color proportional to the substance you want to measure. Hach s unique color comparator uses continuous gradient, calibrated color discs to eliminate time-consuming and inaccurate interpolation between individual color standards. Convenient Reagent Packaging Hach reagents are developed specifically for use in our compact, easy-to-use systems. If several reagents are needed in a single test, our chemists have often found ways to combine them in a single reagent package. Pillows Hach packages many reagents in convenient polyethylene or foil powder pillows. Pillow- or foil-packed reagents are protected from moisture and air, and are safer to handle. AccuVac Ampuls AccuVac optical quality glass ampuls are fast, easy to use, and eliminate sample cell clean-up. Packed under vacuum, each ampul contains the exact amount of reagent(s) for a single test. 6

9 Additional equipment for water quality testing Complete your test kit or portable laboratory with time-saving meters, instruments, test kits, and accessories available from Hach. AccuVac Ampul Field Test Kits AccuVac Ampul field test kits provide fast, simple measurement and immediate, accurate results. Reagent is contained in a vacuum vial. Immersing the vial and snapping the tip draws in a measured sample, where it reacts to develop color. A color wheel provides color comparison with a sample blank and the reacted sample, with direct readout of DO. AccuVac DO Kit, High-Range (0-15 mg/l) AccuVac Dissolved Oxygen Sampler Also available is a sampler designed specifically for vacuum-sealed AccuVac Ampuls. If you are performing colorimetric dissolved oxygen measurement with AccuVac Ampuls, the new DO Sampler will save time and effort. When the sampler is immersed, the operator activates a pneumatic piston which snaps the AccuVac s prescored tip. The Ampul, which serves both as measuring vial and cuvette, fills automatically and is ready for measurement. AccuVac DO Sampler Dissolved Oxygen Meter The DO175 is a very capable instrument for lab or field measurement of dissolved oxygen from 0 to 20 mg/l. It comes with probe, electrolyte, beakers, manual and other accessories in a durable carrying case. The instrument offers easy calibration, RS232 output, and internal datalogging for simplified field work. DO175 Dissolved Oxygen Meter Dissolved Oxygen Sampler Dissolved oxygen profiles require that samples taken at various depths be free of interference by surface contaminants. The Hach sampler, complete with a 3-m (10') brass chain and 60-mL, glass-stoppered sample bottle is ideal. Constructed of PVC, it will not rust or corrode. Dissolved Oxygen Sampler

10 Comprehensive systems for analysis A world leader in simplified quantitative analysis, Hach offers a comprehensive line of packaged test systems for food and feed, soil, and microbiological analyses. These systems, developed by an expert staff of research scientists, are backed by step-by-step testing procedures and are designed to the most exacting specifications. Complete ordering information and descriptions of available products are detailed in our catalogs. To receive your free copies, simply return the inserted reply card to the Hach office or authorized distributor serving you. Test Kits Measure Everything from A to Z Hach offers over 200 different colorimetric and titrimetric procedures to measure everything from acidity to zinc. Each kit includes all necessary apparatus, step-by-step instructions and unit-dose reagents for consistent results. Soil Analysis Nutrients and contaminants contained in soil often have a dramatic influence on the water quality of fish and crab ponds. Because analytical methods will vary depending on the type of soil and the geographic location, it is important to choose the extractants, analytical reagents and methods most appropriate for your soil. Customized analytical testing systems from Hach will help you assess and correct environmental factors which influence production. Simply choose the system best suited to your needs. All feature ph and major nutrient and soil fertility determinations. Microbiological Analysis of Shellfish Microbiological analysis of shellfish is an important gauge of product quality. The presence of Escherichia coli (E. coli) indicates fecal pollution and suggests that other microorganisms of fecal origin, including many disease-producing organisms, may be present. Shellfish tested by APHA (American Public Health Association) methods, however, often produce a large number of false positives. As a result, thousands of dollars are lost for each day shellfish are unnecessarily quarantined. Hach has developed a simple method for the identification and enumeration of E. coli that is faster, less expensive and more sensitive than the APHA-sanctioned method. Use of 4-methylumbelliferyl-ß-D-glucuronide (MUG) reagent can produce savings for shellfish processors by eliminating unnecessary quarantines. 10

11 Monitor critical water quality tests The tests included in Hach s aquaculture kits and portable laboratories are also available individually. Choose single-parameter kits to measure the following if your testing needs are limited to specific parameters. Complete specifications and ordering information are detailed in the adjoining table. Acidity Acidity is usually caused by the presence of mineral acids, salts of strong acids or free carbon dioxide. Although organic acids of natural origin are usually not a problem, mineral acid pollution is detrimental to fish. Alkalinity Alkalinity buffers the water and prevents sudden changes in ph. Alkalinity levels of 100 to 120 mg/l with ph values between 7 and 8 generally are recognized as best for support of diversified aquatic life. Ammonia Ammonia can be toxic to fish at high ph and low dissolved oxygen levels. It decreases the ability of fish to take oxygen into the blood and can cause suffocation. Ammonia levels as low as 0.06 mg/l can damage gills, reduce feeding and impair natural functions. Carbon Dioxide Toxicity of carbon dioxide varies by fish type, water temperature and dissolved oxygen content. In some cases, carbon dioxide can have beneficial effects by lowering the ph and reducing ammonia toxicity. Stressful to fish, carbon dioxide hinders oxygen uptake and has a marked effect on fish behavior. Chloride Effects of chloride are closely related to total salinity and its effects on the ability of fish to take up oxygen. Freshwater fish cannot tolerate sharp changes in salinity. For some fish, 400 mg/l chloride can be harmful. Chloride can be beneficial where nitrite levels tend to be high. Often added to catfish ponds, chloride will control the uptake of nitrite by the fish. Copper Copper may exist in natural waters as a soluble salt or suspended solid. A small amount is essential for plants and animals, and concentrations exceeding 0.1 mg/l are useful for controlling algae and plankton growth. In saltwater aquaria, copper (in the form of copper sulfate) is often used as a treatment for parasite-infested fish. Though saltwater fish are tolerant to high levels of copper, the dosage should not exceed 0.25 mg/l. Dissolved Oxygen As the most critical parameter for a healthy fish environment, dissolved oxygen must be measured frequently. Oxygen requirements of the fish vary with the species and age of the fish, prior acclimatization, temperature and the concentrations of other substances in the water. Supersaturation also can be detrimental to fish production. Hardness Soft water increases the sensitivity of fish to toxic metals, so some hardness is beneficial. However, excess hardness in aquaria can limit fish growth. Nitrite Nitrites are toxic to fish and should be monitored closely, particularly when high-poundage production is an objective. Brown blood disease, a problem in catfish farming, is caused by toxic levels of nitrites which can occur when chloride and oxygen levels are too low. High nitrite levels also are detrimental to the oxygen supply because plankton growth is stimulated. ph ph controls the degree of dissociation of many substances. The optimum range for any particular kind of fish depends on temperature, dissolved oxygen, prior acclimatization and the content of various anions and cations. In most cases, a ph range of 6.5 to 8.2 is suitable. Phosphorus Phosphate enters water supplies from soil run-off, industrial operations, and sewage. Although necessary for biological growth, too much phosphate can cause excessive growth of algae, and may lead to eutrophication. Temperature High temperature can be detrimental to fish for a number of reasons. Not only is there a maximum temperature at which fish can live, but the solubility of oxygen in water, along with its availability to the fish, diminishes at high temperatures. Furthermore, the oxygen demand of fish and other aquatic life increases as the temperature rises. Sudden temperature changes, either up or down, are likely to be harmful. Turbidity This general characterization of water quality may be correlated to the performance of water filtration. Many fish species cannot tolerate high turbidity. 11
