"TriOS microFlu-Chl fluorometer"@en . . "SDN:L22::TOOL1803" . "The microFlu-Chl is a low cost, miniaturised submersible fluorometer designed for high precision measurements of chlorophyll-a. The instrument features an environmentally neutral anti-fouling nano-coating, and is low power consuming to enable long-term use. Applications include monitoring in rivers, lakes and marine settings, particularly for waste water monitoring. Internal reference measurement of the emitted light compensates ageing effects of the high-efficient LEDs, used for fluorescence excitation. The instrument is available with a standard 500 m depth rating, or an optional 6,000 m deep sea version, both of which can operate in a temperature range of 0 - 40 degC. The ultra-bright blue LEDs have a peak excitation wavelength of 470 nm and the detector a detection wavelength peak of 685 nm and a 20 nm full width at half maximum (FWHM)."@en . .
