Features and Benefits
| Main features: • Two built-in Peltier thermostats for density and refractive index measuring cell. • Fully automatic viscosity correction for the density measurement. • Memory cards available for method transfer and data storage. • 9 user methods (+1 for adjustment). • Automation: sampling pump SC1 or sample changer SC30 required. • Up to two calculation formulas or tables per method may be entered to calculate results based on the measured density, the refractive index or both values. • Barcode reader connection to easy read in sample ID and operator names. • Connection to computer for data handling. • If required, one of the two measuring cells may be deactivated for the measurements, instrument checks and adjustments. |
| GLP/GMP: • Adjustment with air & water or certified standards. • Special CHECK function for regular instrument check. • The last 10 CHECK and ADJUSTMENT data are stored and can be recalled and printed out anytime. • Printout of the results with all important data like operator name, date, time and serial number of the instrument. |
