Algae Torch
BBE Algae Torch

Product Features
  • BBE Algae Torch for the simultaneous quantification of the chlorophyll-a content of cyanobacteria and the total chlorophyll content of microalgae in water.
  • A complete measurement needs less than 20 seconds.
  • No sampling or preparation is necessary.
  • Measurement of algal concentrations via fluorescence
  • The intensity of the chlorophyll fluorescence is used to calculate the different algae as chlorophyll-a, here blue-green algae (cyanobacteria) and total microalgae.
  • The results are shown immediately on the display and stored in the internal memory.
  • An encapsulated USB port enables subsequent data transfer to a PC.
  • Automatic turbidity correction.
  • The instrument is deployable down to depth of 10 m (optionally 100 m).
  • Internal rechargeable batteries.

Dissolved Oxygen Sensors - Greenspan DO100, DO3000
