CHS UVSens is a small and light photometer designed for measuring organic water pollution. Measurement of water quality parameters takes place on the basis of absorbed light with a wavelength of 254 nm .
A complex mixture of organic components, commonly found in water, causes problems in water management
Many of these substances absorb UV radiation of 254 nm
We can determine these substances by means of radiation absorption
CHS UVSens – fast and safe optical measurement
Amount of light passed through the sample = transitance
Amount of light absorbed = absorbance [2-log 10 (UVT)]
Spectral absorption coefficient (UV 254)
Specific UV absorbance (UVA/DOC)
The photometer allows two-point calibration. Calibration, or the conversion of the UV 254 nm absorbance value to the required total parameter depends on the composition/origin of the water.
Different locations require their own calibrations
Some locations may need multiple calibrations depending on changing conditions (e.g. season)
