History

More than three decades have passed since the appearance of the first 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 AQUALYTIC. Our range of photometer systems extends from the AL200 in a pocket sized format, AL250 for measuring a single parameter, through the AL250+ for multiple parameters, to the AL800 spectrophotometer.

The AL450 offers a wide variety of pre-programmed methods and is therefore suitable for the demands of modern water and drinking water analysis.

The latest development involves a photometer system, the mobile laboratory photometer AL400. All the parameters which can be measured with AQUALYTIC photometer systems are set out in the table. This table also explains what parameters can be measured with which photometer system.

The principle of photometry

When specific reagents are added, the water sample takes on a degree of coloration that is proportional 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 absorbed by the test substance. The photometer determines the coloration of the sample by measuring 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 displays the result.
