Quality Measurements with SEBA Checker-2
The SEBA Multi-parameter system has been developed as a mobile field laboratory especially for
determination of water quality parameters in surface water.
The has an extremely compact design, easy operation with fast and precise acquisition of various 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.
Checker-2 in Detail
Display
3-lines Display with background lighting for clear indication of current measuring values.
Operation
The instrument can be operated via 3 watertight keys on the front. It is very user-friendly and menuguided.
SEBA-HDA
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.
Read-out and setting of measuring frequency via RS 232-interface with SEBA-HDA or laptop.
RS 232 Interface & Charging
for operation of the data logger, adjustment and calibration of the multiparameter sensors.
Charging of the internal batteries with included charger
Multiparameter Sensor
Double plug-in, maintenance-friendly high-quality-steel probe (MPS-D3, MPS-D8) or single plug-in plastic probe MPS-K16 for connection to Checker-2 or KLL-Q-2.
Individually configurable with various sensors (e.g pH, O , conductivity etc.)
For a detailed description of possible configurations refer to our Water Quality Monitoring brochure.
