Product Description
Measurement items
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
- Full support for various country pharmaceutical pure water guidelines(USP/EP/JP/CP)
- Customizable auto-hold function for calibration and measurement
- Simultaneous connection to a GLP/GMP compatible and PC
- Degital memory: Maximum 2,000 sets of measurement data can be recorded
- USB-PC communication and USB memory
- Multi-language support(Japanese, English, Chinese, Korean)
- FDA 21 CFR Part11
