The Hanna Instruments HI 83099 chemical oxygen demand (COD) and multiparameter bench photometer measures water quality for 47 parameters, has an LCD screen, automatic shutoff, on-screen instructions and a USB port for computer and printer connectivity. 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. On-screen instructions aid in routine operation. This meter is often used in municipal and industrial wastewater testing.
Dimensions are 235 x 200 x 110 mm/9.2 x 7.87 x 4.33 inches (H x W x D), and the meter weighs 0.9 kg (2 lb). (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.) HI 83099 operates on an external 12V power adapter with a 2 m cord and a 115V plug, or built-in rechargeable battery (included). The meter comes with a sample preparation kit that includes a graduated cylinder, cuvettes, beakers, syringes, a funnel, filter discs, a spoon, pipettes, and carbon powder packets. It uses liquid or powder reagents (sold separately).
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 cuvette. The meter uses the difference to calculate the concentration of the test element. For surface testing, a surface is illuminated with white light, and the photometer measures the luminosity of the reflected light. Photometers are commonly used in water quality, agricultural, horticultural, and industrial applications to measure the amount of minerals and chemicals in samples, and for checking water and beverages, such as beer and wine, for consistency.
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.
