Benthic chamberMini Micro Profilers
A novel portable instrument has been designed for in-situ
microsensor measurements. The micro profiler, which can be equipped
with microsensors for measurements of oxygen, pH, sulphide (S
-- or H2S) and temperature, is ideal for a
wide range of applications including:
- Oxygen respiration.
- Benthic primary production.
- Quantification of sulphide oxidation and sulphate reduction by measurement with a sulphide (gas or ion) microsensor for use inbio-filmsand sediments.
Profiling measurements can be carried out with a spatial
resolution of 50 µm in numerous locations including:
- At the sediment-water interface (from tidal flats to 100 m water depth).
- In bio-films, for studying the transformation of organic matter.
- Under ice, for studying respiration and primary production of ice-algae.
Weight, in air: 10 kg
Weight, in water: 8 kg
Total height: 1,0 m
Distance between feet: 0,75 m
The mini microprofilers are developed in cooperation
