Compact fluorometer nanoFlu

nanoFlu fluorometers are low-priced, submersible miniaturized fluorometers for highly precise and selective measurement of CDOM (colored dissolved organic matter, yellow substances), chlorophyll a or phycocyanin in cyanobacteria. Long-term stability of measurements is ensured by the combination of low power consumption and innovative coating of the optical window, as an energy efficient and environmentally friendly anti-fouling solution. The devices can be used in diverse applications for the monitoring of sea and river waters, as well as in drinking- and wastewater treatment systems. Internal reference signals of the high performance LEDs used for fluorescence excitation compensate aging effects and temperature influences. High sensitivity Nano coating Fast data acquisition Electronic light compensation Compact size Low power consumption Low costs Measurement technology - - light source: LED detector: Photo diodes Measurement principle - Fluorescence Parameter - CDOM [μg/L] or chlorophyll a [μg/L] or phycocyanin [μg/L] or rhodamine [μg/L] or fluorescein [μg/L] Measuring range - 0...200 µg/L 0...200 ppb Measurement accuracy - ±5 % Turbidity compensation - No Data logger - No T100 response time - 6 s Measurement interval - 3 s Housing material - Stainless steel (1.4571/1.4404) or titanium (3.7035) Dimensions (L x Ø) - 171 mm x 36 mm - ~ 6.1˝ x 1.4˝ Weight - stainless steel: 0.5 kg titanium: 0.4 kg - ~ 1.1 lbs ~ 0.9 lbs Interface - digital: Ethernet (TCP/IP) RS-232 or RS-485 (Modbus RTU) Power consumption - typical < 1 W Power supply - 12...24 VDC (± 10 %)
