A photometer is used in wastewater, drinking water and environmental analysis to
determinate the concentration of dissolved substances.

For this purpose, specific reagents are added to the dissolved substance to convert it into a measurable color. The color results from the absorption of a certain proportion (wavelengths) of the white light, and hence the measuring is done at the wavelength with the largest absorption.

Whithin a linear range the degree of light absorption can be translated into concentration. Thus, photometers and test sets make up a system whose components are matched optimally.

These photometers provide method data for every test. All necessary settings, e.g. wavelength, calibration slopes, conversion factors, blank value (= the own color of a solution), etc. are set automatically.

photoLab ® S6
Standard instrument with 6 wavelengths, for all routine determinations in reaction cuvettes (16 mm), especially for wastewater and drinking water.

photoLab ® S12
Advanced instrument with 12 wavelengths for test sets in round and in rectangular cuvettes, for wide measuring ranges and low concentrations. In addition, 50 user-defined methods and Kinetics measurements are possible.

photoLab ® Spektral
High-grade variable spectral photometer with Zeiss optics for all routine and special tasks in the VIS range: Test sets for round and rectangular cuvettes, Kinetics measure-ments, recording of absorption and transmission spectrums, as well as 100 user-defined methods with freely selectable wavelength between 330 and 850 nm. Including software Multi/ACHAT II for a comfortable data management and convenient calibration of user-defined methods.
