Trilogy

Trilogy® provides you with excellent sensitivity and measurement range. The all solid-state design ensures you will make reliable and repeatable readings.

Fluorescence modules are available for chlorophyll a, (extractive acidification and non-acidification plus in vivo), rhodamine and fluorescein dye, cyanobacteria (phycocyanin and phycoerythrin pigments), CDOM/FDOM, optical brighteners and ammonium. For extracted chlorophyll measurements using EPA 445, Trilogy® automatically calculates the concentration using the filtered and solvent volumes. The Turbidity Module uses an IR LED with a wavelength of 860 nm to meet ISO 7027 requirements for Turbidity water quality measurements.
