PRINCIPLE OF OPERATION
The color of every object we see is determined by a process of
absorption and emission of the electromagnetic radiation (light) of its
molecules.
Colorimetric analysis is based on the principle that specific compounds
react with others and form a color, the intensity of which is
proportional to the concentration of the substance to be measured.
When a substance is exposed to a beam of light of intensity I
o
, a
portion of the radiation is absorbed by the substance's molecules and
a radiation of intensity I, lower than I
o
, is emitted.

GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
The Hanna Instruments Ion Specific Meters are portable, microproces-
sor-based colorimeters that measure the ion content in water and
waste waters.
The meters use an exclusive positive-locking system to ensure that the
cuvet is in the same place every time it is placed into the measure-
ment cell.
The reagents are in liquid or powder form and are supplied in bottles
or in packets. The amount of reagent is precisely dosed to ensure
maximum repeatability.
Display codes aid the user in routine operations.
The meters have an auto-shut off feature that will turn the meter off
after 10 minutes of non-use.
