The Hanna Instruments HI 96750C potassium portable photometer measures potassium content in water in the low and medium range, has a calibration check function, automatic shutoff, an LCD screen, and on-screen instructions. The calibration check function (CalCheck) validates instrument performance. An automatic shutoff feature turns the meter off after 10 minutes of non-use in measurement mode, and after one hour of non-use in calibration mode, to help extend the life of the meter. Automated instructions on the LCD screen aid in routine operation. The meter is splashproof, and the lamp and filter are protected from dust and dirt by a transparent cup, making it suitable for field applications. The device uses a positive-locking system to help ensure consistent positioning of the cuvette. Potassium photometers measure potassium content in drinking and surface water samples, and are commonly used in the water quality, horticultural, and agricultural industries.

Power source is a 9V battery (included). A reaction between the reagent (sold separately) and potassium in a sample causes a distinct white cloudiness to appear, which is measured by the photometer. The meter uses the tetraphenylborate method. Photometers measure the light intensity of solutions or surfaces. For solution testing, a sample and reagent are placed in a cuvette in the photometer. The photometer transmits l...

SAMs (Single Analyte Meters): Value and Convenience Single Analyte Meters (SAMs) provide unprecedented economy, simplicity, and accuracy for dedicated photometers. SAMs provide results equivalent to other meters and probes costing much more. SAM Photometer (Single-Analyte Photometer) Kit comes in a plastic case and contains everything needed to perform 30 tests: K-2513 Vacu-vials Kit, SAM Photometer, 2 AA batteries, and instructions. Methods Because of its strong oxidizing properties, chlorine is an excellent biocide used to treat potable waters, municipal wastes, and swimming pools. When used to treat potable water, chlorine helps alleviate the adverse effects of iron, manganese, ammonia, and sulfide. The Maximum Residual Disinfectant Level for chlorine is 4 mg/L in drinking water. The DPD Method References: USEPA Methods for Chemical Analysis of Water and Wastes, Method 330.5 (1983). APHA Standard Methods, 21st ed., Method 4500-Cl G (2005). In the USEPA-approved DPD methodology, free chlorine reacts with DPD to form a pink product. When ammonia or amines are present, some of the chlorine may exist as combined chlorine. Combined chlorine will not interfere with the free chlorine results, provided the readings are taken at one minute. To determine total chlorine (the sum of free and combined), use the A-2500 Activator Solution (potassium iodide) supplied in the kit. Results are expressed as ppm (mg/L) Cl2.

The HI 832742 is a portable photometer for measuring total phenols, color density and tint of a liquid. These types of meters are often used in the beverage making process, especially in wine and beer production. The photometer is equipped with three optical channels, each with a specialized tungsten light source and a narrow band interference filter (420 nm, 525 nm, 610 nm). The meter automatically calculates color density, tint and total phenols, eliminating the need for time consuming calculations. Color density range is 0.000 to 1.000 (white, + or - 5%) and 0.00 to 15.00 (red, + or - 4%). Tint range is 0.00 to 9.99 (white), 0.00 to 9.99 (red), + or - 4%. Phenol range is 0.000 to 0.750 (white) and 0.00 to 5.00 (red). The device operates on four 1.5 V AA batteries or a 12 VDC adapter. Dimensions are 225 x 85 x 80 mm and it weighs 500 g. Photometers for color density and phenols are used in the beverage making process to ensure quality and preferred taste. Phenolic compounds are measured in the winemaking process because they affect the color, odor, and reduce the oxygen content of wine.
