Mobile field laboratory with electric cable contact gauge for measuring the water level, temperature and other water quality parameters (e.g. oxygen, pH, conductivity, redox potential, turbidity) in groundwater and surface waters SEBA Plug-in System for coupling with SEBA multiparameter sondes of the MPS-D3/D8/K16 Printed tubular cable with cm/dm/m-scaling, available from 30 m to max. 400 m in length 3-line backlit LCD display Integrated logger for manual and / or automatic storage of measured values (optional) Individually configurable: The KLL-Q-2 can be adapted and tailored to the desired measuring task. The choices are cable drums of varying sizes with cable lengths of 30 to 400 meters and three multiparameter sensors (MPS-D3/D8/K16), which can be equipped with a variety of water quality sensors. Versatile applications: The KLL-Q-2 is suitable for the sampling of lakes and reservoirs as well as for monitoring of groundwater measuring points starting from 2" pipe diameter. Efficient: The printed round cable allows an exact lowering of multiparameter probe to the desired measuring depth. Thus, profile measurements can be carried out in a very short time. Optionally, an integrated logger is available which automatically stores all relevant measurement data manually by pressing a key as at predetermined intervals. Compact and user-friendly: The KLL-Q-2 with its robust aluminum support frame can be easily transported from one measuring point to another. For operation and display, the user is equipped with a membrane keypad and LCD.
