Quality Measuring with KLL-Q-2

The SEBA-KLL, type is a unique mobile field laboratory for measurements of water quality at groundwater or surface water measuring sites. Suitable for 50mm (2”) diameter wells. The instrument has an extremely compact design, easy operation with fast and precise acquisition of many water quality parameters. The current measured values are clearly displayed.
Optionally, the instrument can be equipped with an integrated data logger with a storage capacity of up to 70,000 values for an automatic or manual data recording. By default, the is supplied with an accoustic signal device when the sensor touches the water surface. The new graduated round-cable with robust PE-covering (laserprinted, cm/dm/m) is fade proof and abrasion resistant.

KLL-Q-2 in Detail

3-lines Display with background lighting for clear indication of current measuring values.

The instrument can be operated via 3 keys on the front. It is very user-friendly and menu-guided.

RS232 Interface
Comfortable calibration of Multiparameter sensors via operation Software SEBAConfig and your PC/Notebook.

Your alternative to using a Notebook for programming, read-out of the stored files as well as for local visualisation of measuring data.

Data Logger

Full data logger functionality (optional) is possible for the automatic storage of up to 70,000 measured values. Instant logs can be obtained manually at the push of a button, suitable for quick assimilation of water quality profiles.


Due to the drum-combined supporting-frame the Multiparameterprobe can easily be lowered with our new improved laser-printed round-cable.


The comfortable transport-container guarantees for a fast readiness as well as for a safe storage of the probes.

Multiparameter Sensor

Plug-in, maintenance-friendly high-quality-steel probe for connection to KLL-Q-2 or MPS-Checker.
Individually configurable with different sensor-systems (e.g. pH, O , conductivity etc.)

For a detailed description of the Multiparameterprobe please see our Water Quality Monitoring brochure.
