Submersible Fluorometer is designed to measure fluorescence of underwater organisms - plants, corals, or seaweed.
The measuring compartment is equipped with a holder that allows easy manipulation under the water. Maximum operating depth of the instrument is ca 1 meter (40 inches). The fluorometer is supplied with three sets of light-emitting diodes and a PIN diode detector with 1 MHz/16-bit AD converter and software controlled gain and integration time. The light-emitting diodes can generate:
- Measuring flashes, typically 2-5 µs long. Standard color is red-orange (λmax=617 nm).
- Single-turnover saturating flashes, typically 20-50 µs long. Standard color is red (λmax=630 nm).
- Continuous actinic light of the maximum intensity of 1,500 µmol(photons).m-2.s-1. Standard color is red (λmax=630 nm).

Light intensities and timing are software controlled, separately for each LED set. The data are processed and the instrument is controlled by the Windows 95/98/2000/XP compatible FluorWin software.
- Creation and archivation of experimental protocols.
- FluorWin Wizard for automated protocols.
- Retrieval and export of experimental data.
- Data manipulation and visualization.
