Hanna Instruments HI96727 Color of Water Portable Photometer, 7-19/32" Length x 4-3/32" Width x 2-11/16" Height, 0 to 500 PCU, 10 PCU Resolution, LCD Display, 9V

User calibration. Certified calibration and verification standards. BEPS (battery error prevention system). Timer function. Auto shut-off. GLP Features. Color together with odor, taste and turbidity form an integral part of our sensory system. Testing for color can be a quick and easy test which often reflects the amount of organic material in the water, although certain inorganic components like iron or manganese can also impart color. The HI 96727 measures the true and apparent color in water and wastewater in the 0 to 500 PCU (Platinum Cobalt Units) range. The HI 96727 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 a cuvette with a larger neck making it easier to add both sample and reagents. The cuvette is made from special optical glass to obtain best results. Range: 0 to 500 platinum cobalt units. Resolution: 10 platinum cobalt units. Accuracy: +/-10 PCU +/-5 percent of reading at 25 degree celsius. Light source: tungsten lamp. Light detection: silicon photocell with narrow band interference filter at 420 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: colorimetic platinum cobalt units.
