Ver.5.0 – Revision March 2022
The technique used is UV induced fluorescence with the
capability of detecting the PAH concentration in μg/l
(ppb).
Excitation wavelength: 254 +/-10nm
Detection wavelength: 360 +/- 50nm
The PAH measurement is compensated for the effects of
turbidity by means of a turbidity compensation formula
and input from the turbidity sensor module G6120.
Low range: 0...100 µg/l phenanthrene equivalence, or
High range: 0...800 µg/l phenanthrene equivalence or
Dual range: 0...100/800 µg/l phenanthrene equivalence
To be specified upon order.
