Nitrite
LR Checker (0-999 ppb)
The
Hanna Nitrite Low-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 Low 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-707 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-707 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
