The Hanna Instruments 95747-03 copper, low range, reagent, for use with the HI 96747 Copper, Low Range, Portable Photometer, contains the proper dosage for 300 tests that measure the copper content using the bicinchoninate method in water samples in the 0.000 to 1.500 mg/L range. HI 95747-03 contains 300 odorless, white to yellow powder copper reagent packets, for 300 tests. A reaction between the reagent and copper in a sample causes a distinct purple color to appear, which is measured by the photometer. The photometer uses an adaption of the United States Environmental Protection Agency (USEPA)-approved bicinchoninate method. Reagents are used in photometers to measure the light intensity of solutions or surfaces. The reagent is mixed with the sample and placed in the photometer, which then produces a reading. Reagents are commonly used in the water quality, agricultural, and horticultural industries to measure the amount of minerals and chemicals in water samples. Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards. What’s in the Box? 300 reagent packets, HI 95747-03 Safety data sheet

The disinfectant properties of iodine have led to its use as an alternative to chlorine and bromine. Unlike chlorinated pools, water treated with iodine decreases eye irritation among swimmers, and provides a level of disinfection more stable to adverse conditions. However, its toxic and corrosive properties and the difficulties of dissolving it in water has limited it’s widespread acceptance. One of its most common applications is in poultry industry process water. The cuvette is made from special optical glass to obtain best results. The HI 96718 measures the iodine content in water samples in the 0.0 to 12.5 milligrams per liter (ppm) range. The method is an adaptation of the standard methods for the examination of water and wastewater, 18th edition, DPD method. Cal Check. User calibration. Certified calibration and verification standards. BEPS (battery error prevention system). Timer function. Auto shut-off. GLP Features. Range: 0.0 to 12.5 milligrams per liter. Resolution: 0.1 milligrams per liter. Accuracy: +/-0.1 milligrams per liter +/-5 percent of reading at 25 degree celsius. Light source: tungsten lamp.

Nickel is commonly utilized by the electroplating industry in processes utilizing stainless steel, cobalt or nickel alloys. Nickel is also used in batteries, fuel cells and hydrogenation of vegetable oils in the food industry. This meter uses an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell. The cuvette has a very important role because it is an optical element and thus requires particular attention. It is important that both, the measurement and the calibration (zeroing) cuvettes, are optically identical to provide the same measurement conditions. User calibration.
