Color of Water Series

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 Lighting Units provide 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.

Features of the Color of Water Series include:
-Available in 3 path lengths
-Long 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 chlorine
-An integrated prism brings the “sample” and “standard” together into one field of view
-Simple one button press operation (the light is on only when you need it to be) increases bulb light
-This guarantees correct lighting conditions 24 hours a day
-Ergonomic design that allows comparators to be used in a comfortable position
