Hanna Instruments HI96731 Zinc Portable Photometer with Sample Cuvettes, 7-19/32" Length x 4-3/32" Width x 2-11/16" Height, 0.00 - 3.00mg/L, 0.01mg/L Resolution, 9V Battery

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.
