Applications of Lovibond® reagents » 
Reagents for photometry »
Several decades have passed since the appearance of the first Lovibond® PC 100 photometer system. Since that time, Tintometer has become a world-famous name as the manufacturer of photometer systems sold under the brand name of Lovibond®. Our range of photometer systems extends from the MD 100 as hand-held model over the multi parameter photometer MD 200 as desktop model to the SpectroDirect spectrophotometer for laboratories.
The multi-functional PM 600 & 620 photometers provide the answer to all requirements relating to the analysis of water used in modern swimming pools and baths. They offer a wide variety of pre-programmed methods and are therefore suitable for the demands of modern water analysis. All the parameters which can be measured with Lovibond® photometer systems are set out in the table. This table also explains what parameters can be measured with which photometer.

The photometric principle
When specific reagents are added, the water sample takes on a degree of coloration that is pro- portional to the concentration of the parameter being measured. The photometer measures this coloration.
When a light beam passes through the coloured sample, energy with a specific wavelength is ab- sorbed by the test substance. The photometer de- termines the coloration of the sample by measu- ring the transmission or absorption of light of this wavelength (in other words, monochromatic light). The photometer then uses a microprocessor to calculate the required concentration and dis- plays the result.
