PRINCIPLE OF OPERATIONPRINCIPLE OF OPERATION

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

, a

portion of the radiation is absorbed by the substance's molecules and

a radiation of intensity I, lower than I

, 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.
