PHOTOMETRY: Photometers, spectrophotometers, turbidimeters and refractometers.
Measuring equipment for the determination of the main parameters in water (photometer); assessment of the colour formed in samples and display of the concentration value (spectrophotometer); monitoring of water quality in all types of water (turbidity meter) and measurement of total solids in a solution (refractometer).
