The Hanna Instruments HI 96715 ammonia medium range portable photometer measures ammonia-nitrogen (NH3-N) content in water in the medium range (0.00 to 9.99 mg/L), 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 nonuse in measurement mode, and after one hour of nonuse 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. Ammonia photometers measure the ammonia content in water samples, and are commonly used in the water quality industry. Range is 0.00 to 9.99 mg/L. Accuracy is + or - 0.05 mg/L, + or - 5% of reading at 25 degrees C. Resolution is 0.01 mg/L for measurement, and 0.1 mg/L for calibration and validation. Dimensions are 192 x 104 x 69 mm/7.6 x 4.1 x 2.7 inches (H x W x D), and the meter weighs 360 g (12.7 oz.). (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) Power source is a 9V battery (included). A reaction between the reagents (sold separately) and ammonia in a sample causes a distinct yellow color to appear, which is measured by the photometer. The meter uses an adaptation of the ASTM Manual of Water and Environmental Technology, D1426-92, Nessler 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 light through the cuvette, and compares the intensity of the light that shines through to the amount of light that shines through a blank cuvet...

Hydrazine is a liquid chemical substance normally used in high pressure heating plants because of its properties as an oxygen inhibitor. It is added to avoid scaling and corrosion in the plant itself. Hydrazine reacts with dissolved oxygen to yield nitrogen and water, so that hydrazine has the advantage over the sulfite treatment because it does not produce any dissolved solids in the boiled water. Hydrazine is also used in tanks because it controls the growth of bacteria. Other hydrazine uses include: oxygen scavenger for water boiler feed and heating systems to prevent corrosion damage, energy source in fuel elements, reducing agent for the recovery of metals (copper, nickel and others), intermediate in insecticides, herbicides, explosives, plant growth regulators, pharmaceuticals, dyes, flame-retardants, polymerization catalysts and other chemical products, component of photo development. The HI 96704 meter measures the hydrazine content in water samples. The method is an adaptation of the ASTM manual of water and environmental technology, method D1385-88 for natural and treated water. Cal Check. User calibration. Certified calibration and verification standards. BEPS (battery error prevention system). Timer function. Auto shut-off. GLP Features. Range: 0 to 400 µgrams per liter. Resolution: 1 µgrams per liter. Accuracy: +/-3 percent FS. Light source: light emitting diode. Light detection: silicon photocell with narrow band interference filter at 466 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 ASTM manual of water and environmental technology, method D1385-88 for natural and treated water.

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 (Single-Analyte Photometer) Kit comes in a cardboard box and contains everything needed to perform 20 tests: R-9423 Instrumental Refill, SAM Photometer, light shield, 4 AAA batteries, screwdriver, and instructions.. The Methylene Blue Method The methylene blue active substances (MBAS) method is used in a 3-minute procedure to measure anionic detergents. The procedure features a unique extraction/sampling technique that eliminates several steps required in other test procedures and provides increased sensitivity. Anionic detergents react with methylene blue to form a blue-colored complex that is extracted into an immiscible organic solvent. Results are expressed in ppm (mg/L) as linear alkylbenzene sulfonate (LAS), equivalent weight 325. Shelf-life: eight months. We recommend stocking quantities that will be used within seven months.
