The colour 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 many substances react with each other and form a colour which can indicate the concentration of the substance to be measured. When a substance is exposed to a beam of light of intensity I0 a portion of the radiation is absorbed by the substance's molecules, and a radiation of intensity I lower than I0 is emitted.
The HI-83203-02 is a multiparameter bench photometer dedicated to Aquaculture analysis. It can measure 13 different parameters using specific liquid or powder reagents, it clearly explains both methods of testing in the instruction booklet and as the unit is not supplied with reagents it is your choice whether you decide to purchase liquid reagents or powder reagents to test with.
The HI-83203-02 measures Ammonia, Chlorine, Copper, Nitrate, Nitrite, DO (Dissolved Oxygen), pH and phosphate.
The HI-83203-02 is supplied complete with Cuvets, batteries, 12VDc adapter and instructions
