Multi-temperature simultaneous analysis, automatic sampling

Herzog's automatic multi-range viscometer HVM 472 measures clear and opaque liquids in just five minutes, with a unique double bath design which enables two simultaneous analyses at two different temperatures. Moreover, a revolutionary autosampler offers a really continuous operation: used sample jars are automatically drained, allowing to add new samples at any time...even in the middle of the analysis! HVM 472 complies with or exceeds ASTM D445 precision requirements. Results can be exported to a printer or LIMS. Add the powerful Herzog Laboratory Information System (HLIS®) software for Windows for an advanced operation and data management.

  • Measures clear and opaque liquids with powerful precision
  • Optional sample preheating station with individual temperature settings for waxy and heavy materials analysis
  • Optional Fast Run capillaries (factor 20 range each) with reduced sample amount (4 ml) and a faster analysis cycle (< 6 min, cleaning included)
  • Immediately displayed results on local digital screen; they can be directed to an optional printer or a computer system automatically or on demand
  • Fast temperature balancing

SIMPLIFIED SMART AUTOMATION

  • Designed for unattended operation
  • Two 26-positions autosamplers (one for each bath)
  • Used sample jars are immediately drained to the easy access tray
  • In the middle of the test new samples can be added
  • System automatically asks the user sample name/ID when new samples are loaded

EFFORTLESS CLEANING PROCESS
