Photometric analysis is a simple and effective mechanism for determining water quality parameters. Get expert digital measurements in both single and multi-parameter formats.  Our photometers cover all major water quality parameters and are suitable for use across a range of applications.

HOW DOES LUMISO WORK?

Lumiso works, like all photometers, by shining light through a sample and measuring the amount of the light that passes through to a detector.

The colour in the sample is usually formed by a reaction with the reagents that have been added to it. The darker the colour of the sample, the less light will make it through to the detector.  Initially all wavelengths of visible light come out of the light source.  These are reduced to a single wavelength using an optical filter. The photometer will measure the light passing through the sample in percentage transmission (%T), and this value is converted to a concentration using the internal calibration of the instrument.
