Color of Water Set 2Includes:711-A2 Nessler Body Set of 2 Nessler Tubes Nessler Illuminator 2 Color of Water Discs (10-90 Pt. Co. Units and 70-250 Pt. Co. Units).Designed for measuring unsaturated samples that are below the sensitivity of a normal, hand-held comparator system, the 711 Nesslerizer System employs longer pathlengths that make it possible to accurately match samples that produce very pale colors visually.The built-in magnifying prism allows the user to easily view the glass color disc standard and the sample to be matched side-by-side. Glass plungers eliminate distracting miniscus curvatures.Correct lighting conditions are essential for accurate color comparison.The Nessler Illuminator provides a constant and stable light using a tungsten halogen lamp and a calibrated color temperature correction filter guaranteeing correct lighting conditions 24 hours a day. This means that reliable test results can be obtained at all times, and under all ambient light conditions.FeaturesLong path lengths allow for the visual measurement of parameters in which very pale colors are produced such as the color of water and low ranges of chlorineAn integrated prism brings the "sample" and "standard" together into one field of viewSimple one button press operation (the light is on only when you need it to be) increases bulb lightThis guarantees correct lighting conditions 24 hours a dayErgonomic design that allows Nesslerizers to be used in a comfortable position Applications: Color of WaterColor Scales: Platinum-Cobalt/Hazen/APHA Color (ASTM D 1209).
