The Hanna Instruments 93751-03 sulfate reagent, for use with the HI 96751 Sulfate Portable Photometer, contains the proper dosage for 300 tests that measure the sulfate content using the turbidimetric method in water samples in the 0 to 150 mg/L range. HI 96751-03 contains 300 odorless, white powder sulfate reagent packets, for 300 tests. A reaction between the reagent and sulfate in a sample causes a distinct white cloudiness to appear, which is measured by the photometer. The meter uses an adaptation of the turbidimetric 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.

Zinc is normally introduced into drinking water through industrial effluents, especially due to dezincification of brass and deterioration of galvanized iron. In addition to drinking water, zinc is measured in surface finishing, boilers and cooling towers, water conditioning, effluent waters and many others. The HI96731 measures the zinc content in water and wastewater in the 0.00 to 3.00 milligrams per liter (ppm) range. The 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. HI96731 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0.00 to 3.00 milligrams per liter pH range. 0.01 milligrams per liter pH resolution. +/-0.03 milligrams per liter +/-3 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 575nm light detector. Adaptation of the standard methods for the examination of water and wastewater, 20th edition, zircon method. 0 to 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. Auto-shut off: after ten minutes of non-use in measurement mode, after one hour of non-use in calibration mode with last reading reminder. Measures 7.6" length by 4.1" width by 2.7" height.

User calibration. Certified calibration and verification standards. BEPS (battery error prevention system). Timer function. Auto shut-off. GLP Features. The HI 96714 meter measures the cyanide concentration in waters. The meter uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell. It is designed to fit cuvettes with a larger neck making it easier to add both sample and reagents. The cuvettes are made from special optical glass to obtain best results. Cyanide is a pollutant that originates mostly from metalurgicaland galvanic industrial plants. Cyanide is poisonous to human nervous system, and it is therefore imperative to monitor and control its level in potable water. Continuous monitoring in waste effluents is required, and cyanide is removed using alkaline chlorination procedure. Due to this, European norm limit the concentration of cyanide in drinking water to 0.05 milligrams per liter , while the EPA has established that the maximum level is not to exceed 0.2 milligrams per liter. Range: 0.000 to 0.200 milligrams per liter. Resolution: 0.001 milligrams per liter. Accuracy: +/-0.005 milligrams per liter +/-3 percent of reading at 25 degree celsius. Light source: tungsten lamp. Light detection: silicon photocell with narrow band interference filter at 610 nm. Battery type/life: 9V/approx. 40 Hours of continuous use; auto-off after 10 minutes of non use. Environment: 0 to 50 degree celsius (32 to 122 degree fahrenheit); RH max 95 percent non-condensing. Measures 7-19/32" length by 4-3/32" width by 2-11/16" height. Method: adaptation of the standard methods for the examination of water and wastewater, 18th edition, pyridine-pyrazolone method.
