Description

Applications
Water Treatment Monitoring
Early detection of potentially harmful algal blooms
Effective control of water treatment chemicals

Online Algae Monitor
The Algae Online Monitor (AOM) is a portable and robust device for online detection and continuous monitoring of photosynthetic microorganisms in natural and artificial water bodies. A variety of cyanobacteria, green and brown algae, diatoms, and other photosynthetic microorganisms are detected. High sensitivity (30 ng Chl/L) allows for early detection of concentrations of many low-lying organisms.

Measured Parameters
FT: Instantaneous Fluorescence
QY: Quantum Yield
OJIP: Fixed Area: Total area above the OJIP fluorescence transient. This parameter correlates with the total change in the OJIP fluorescence signal, the total pigment content, and therefore the cell concentration. Special fluorescence protocol: Fluorescence Flash Induction (FFI)

Programs
Real-time data collection for online medications
Internal data storage and external communication.
Export data to Excel for analysis or visualization applications.
Compatible with Windows 7 or higher
