HVM 472 AUTOMATIC MULTI-INTERVAL VISCOMETER

Simultaneous multi-temperature analysis, automatic sampling

Herzog’s HVM 472 automatic multi-range viscometer measures transparent and opaque liquids in just five minutes, with a unique double bath design that allows for two simultaneous analyses at two different temperatures. In addition, a revolutionary autosampler offers truly continuous operation: used sample vessels are automatically discharged, allowing you to add new samples at any time... even mid-analysis! The HVM 472 meets or exceeds the accuracy requirements of the ASTM D 445. Results can be exported to a printer or LIMS. Add the powerful Herzog Laboratory Information System (HLIS) software for advanced data management and operation.

FAST AND POWERFUL ANALYSIS

• Quick and easy operation in three easy steps; two analyses; two temperatures simultaneously
• Variable temperature selection from 20 ºC to 150 ºC with advanced microprocessor control
