Field equipment

IBED owns a wide variety of state of the art fieldwork equipment  used for field studies on land or in the aquatic environment.

Multi-parameter sensors

Our multi- parameter sensors can simultaneously measure multiple physical as well as biogeochemical parameters in a water phase.

Hydrolab

The Hydrolab is a quality water multiprobe logger designed to be used in fresh, salt and polluted water. The instrument can measures various parameters including: temperature, depth, light intensity, pH, dissolved oxygen, specific conductivity and chlorophyll. The Hydrolab is typically used to obtain depth profiles of these physical and biogeochemical parameters.

Technical Specifications (Hydrolab DS5 or DS4a, Hach Company, Loverland, CO, USA)

  • Parameters: O2, pH, T, depth, Conductivity, CHl-a, Light intensity (PAR)
  • Depth: 50 or 200m cables

Hach HQd

The portable HQd has a rugged, waterproof and flexible design allowing connection of multiple probe parameters to the same meter. It is very suitable for measuring temperature, dissolved oxygen, pH and specific conductivity in the field.

Technical Specifications (HQD, Hach Lange)

  • Parameters: Temp, O2, Conductivity (5m cables) and pH (3m cable)

Spectro-radiometry

Spectro-radiometers are used to measure the spectral power distribution of a light source. From the spectral power distribution, the radiometric, photometric, and colorimetric quantities of light can be determined in order to measure and characterize the light sources.

In our studies the RAMSES is used to measure spectral changes along a vertical water column.

RAMSES

The RAMSES can be used in the laboratory as in the field. Mounted in a frame it can be submerged to a depth of maximal 300m.

Technical Specifications (RAMSES-ACC-VIS, TriOS GmbH, Germany)

  • Spectral range: 320 to 950 nm, spectral accuracy 0.3 nm
  • Inclination and depth sensor
  • Maximum measuring depth: 300 m
