Nitrite
HR Checker (0-150 ppm)
The
Hanna Nitrite High-Range Checker® bridges
the gap between simple chemical test kits and professional
instrumentation. Chemical test kits have limited accuracy and resolution
since they rely upon the human eye to discern differences in color.
Professional instrumentation incorporates a light source such as an LED
or tungsten lamp with a filter and a light sensing detector to precisely
determine absorbance and ion concentration. Professional instrumentation
offers greater resolution and accuracy but can cost hundreds of dollars.
The Hanna Nitrite High-Range Checker® uses
a fixed wavelength LED and silicon photo detector to provide the
accuracy of professional instrumentation at the affordable price of a
chemical test kit.

Operation
The
HI-708 Checker® HC
(Handheld Colorimeter) provides a simple, accurate and cost effective way
to measure nitrite. As an intermediate part of the nitrogen cycle,
nitrites are present in a variety of sources, from drinking water to
industrial water. Due to the harmful effects to the environment and
aquatic life, nitrite levels must be closely monitored. Designed as a more
accurate alternative to chemical test kits, the HI-708 provides quick,
accurate results in four easy steps:
Features
-
Easier to use and more accurate than chemical test kits
-
Dedicated to a single parameter
-
Small size, big convenience
-
Ideal for water quality, environmental, education, aquaculture, boiling
and cooling towers
