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 .
|UVT||Amount of light passed through the sample = transitance|
|UVA||Amount of light absorbed = absorbance [2-log 10 (UVT)]|
|SAC 254||Spectral absorption coefficient (UV 254)|
|SUV||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.
