Ammonia
High Range Checker (0.0-99.9 ppm)
The
Hanna Ammonia High-Range (0 to 99.9 ppm) 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 ion concentration. Professional instrumentation offers greater
resolution and accuracy but can cost hundreds of dollars. The Hanna
Ammonia 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-733 Checker® HC
(Handheld Colorimeter) provides a simple, accurate and cost-effective way
to measure ammonia. Present in water as a component of the nitrogen cycle,
ammonia is excreted from animals and other organisms such as heterotrophic
bacteria, actinomycetes, and fungi during the metabolism of proteins and
amino acids. Generally present in small quantities in unpolluted waters,
higher levels indicate organic pollution and is toxic to aquatic
life. Designed as a more accurate alternative to chemical test kits, the
HI-733 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, aquaculture, education, industrial
