Field devices
We have numerous field devices and probes for the determination of hydrological, physicochemical and microbiological parameters as well as for carrying out marking experiments and hydraulic tests:
Water level, pouring
Several cable light solders, some with conductivity and temperature detection
Numerous pressure probes (Diver) for continuous water level measurement
Vane probe
Flow measuring cells
Several flow cells for measuring physicochemical parameters in surface waters and springs
Multiparameter
Multiparameter measuring instruments (WTW) for measuring pH, redox, oxygen, conductivity, temperature and turbidity
Online measuring instruments from SEBA for the measurement of pH, redox, oxygen, conductivity, temperature, nitrate and turbidity
Spectro::lyser probe (s::can Messtechnik GmbH) for online measurement of nitrate with high temporal resolution
Fluorimetry
6 field fluorimeters for the determination of fluorescence tracers (FL30, FL24) (see marking techniques).
Filter fluorometers (Trilogy, Turner Instruments) for on-site measurement of fluorescent dyes and CDOM
Automatic samplers
