Features
Click here for the dedicated LAQUA website (opens in a new Window)LAQUA DS-70 series measures Conductivity, Resistivity, Salinity, TDS and Temperature simultaneously and the Model DS-72 complies with industrial pharmacopoeias standard (JIS, USP, EP, JP and CP).
The meters’ auto diagnostic function allows the user
to make sure that the instruments will always give high performance and
reliable measurements. Fully GLP/GMP compliant, the LAQUA can be
connected to an external printer. To ensure traceability all results are
recorded together with sample name, user ID and calibration
information.
We offer a comprehensive range of conductivity
electrodes adapted to all type of application and sample. Recognised for
their stability and longevity, HORIBA’s electrodes provide accurate
measurement in all conditions.
LAQUA’s large capacitance touch screen panel:
- Display easy to understand value and functions menus
- Switch between digital real time graphs or analogue displays during measurement with just the flick of a finger.
- Full on-screen support on the meter via an electronic user guide with colour pictures that can be called up at any time, featuring problem solver guide for calibration or measurement.
Functions
- Easy navigation for main unit and electrode inspections.(DS-72)
- Full support for various country pharmaceutical pure water guidelines(USP/EP/JP/CP)(DS-72)
