1 Introduction

1.1 Description

The

Aqua

Fluor

is a lightweight, handheld fluorometer/turbidimeter ideal for field use. Its

small size and durability make the

Aqua

Fluor

perfect for the user who needs quick

measurements away from the laboratory. Dual-channel capability allows users to measure
fluorescence and turbidity of one sample.

The

Aqua

Fluor

can be configured with any two channels as follows:

in vivo

Chlorophyll,

Extracted Chlorophyll, Cyanobacteria (Phycocyanin or Phycoerythrin), Turbidity, Rhodamine
WT, Fluorescein, Ammonium, CDOM/FDOM, or Optical Brighteners.
