Equipment for Hydrogeology

Powerful and reliable MP-1 submersible pump for pumping tests, tracer tests and water sampling. The pump is capable to operate with pumping rates of up to 34 litres per minute and pumping depths of 50 meters.

• In-Situ multi-parameter sensor (temperature, electrical conductivity, pH, oxygen, redox)
• Pressure transducer (RugedTroll100, Eijkelkamp Micro-Diver)
• Hand-held sensors for physicochemical parameters (temperature, elec. conductivity, pH, oxygen, redox)

Continuous temperature monitoring along a fiber optic cable up to 2km.

• AP Sensing Linear Pro N4386 control and monitoring unit
• Ambient temperature monitoring, thermal tracer testing
• The DTS system monitors the temperature distribution along a fiber optic cable with high precision.

Portable LED photometer with 6 wavelengths for environmental monitoring and extensive water and routine analysis in (mobile) service laboratories.

The impeller is moved by the water flow and through this the flow velocity of the water can be determined.

Due to the magnetic-inductive measuring principle, the device can also be used where hydrological measuring vanes or Doppler measuring systems reach their limits, e.g. with low flow velocities, heavily weedy waters as well as flowing waters with low suspended sediment content.

Here the undisturbed sample is taken for the lysimeter.

This is used to carry out the column test from the unsaturated zone with artificial irrigation.

Permeability measurements on soil samples in the laboratory

High-resolution hydraulic tests, tomographic tracer tests.

The packer system isolates specific borehole depth intervals for targeted sampling and injection. Equipped with the pneumatic slug test head, the system can be used for pneumatic slug testing at selected levels and for hydraulic tomography applications.

The 3D Printer allows to create precisely fitting individual parts for use in and with research equipment.

Pressure sensors record the groundwater level in wells over long periods of time.

To stationary record pressure and temperature in deep aquifers.

Soil moisture sensors measure the water content of soil, which allows to determine the groundwater recharge.

The turbidity of water is a general quality parameter, it is caused by the presence of small free-floating particles.

Using spectral measurements, the sensor can determine the concentration of nitrate, dissolved and total organic carbon in the water.
