very pale colors are produced such as the
color of water and low ranges of chlorine
INTEGRATED PRISM
• Brings “Sample” and “Standard”
together into one field of view for side by
side viewing
NESSLER ILLUMINATOR

EU style plugs to ensure usability
worldwide
• Low voltage - voltage is maintained at
12V, ensuring that no high voltages are
present near liquid samples
• Ergonomic design that allows Nesslerizers
to be used in a comfortable position
LIGHT SOURCE
• Simple one button press operation --
the light is on only when you need it to
be -- increases bulb life
• Provides a constant and stable light
using a tungsten halogen lamp
and a calibrated color temperature
correction filter.
• This guarantees correct lighting
conditions 24 hours a day.

711-A2 Nesslerizer System
Designed for measuring unsaturated samples that are below the sensitivity of a normal, hand-held
comparator system, the 711-A2 Nesslerizer System employs a 113 mm pathlength that makes 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.
