Cinematic viscosity automatic analysis complying with or exceeding ASTM D445 requirements. HVU Series by Herzog offers a really standalone operation with exceptional temperature range and bath stability. Analyses two samples simultaneously using standard Ubbelohde capillary tubes Meniscus detection systems with near-infrared (NIR) or thermal NTC precisely measure flow properties also of more difficult sample kinds, while an automatic tube cleaning system incorporates Karlez™ gaskets, resistant to aggressive solvents such as toluene or acetone. The complete cycle duration, including the automatic cleaning, varies from 30 to 40 minutes. Results can be exported to a printer or LIMS immediately or on demand. Add the powerful Herzog Laboratory Information System (HLIS®) software for Windows for an advanced operation and data management.

APPLICATIONS: 

Viscosity:

  • LIQUID PETROLEUM PRODUCTS
  • AVIO JET FUELS
  • WATER CONTAINING EMULSIONS
  • LUBRICANTS
  • EXHAUST OILS
  • POLYMERS
  • RESIDUALS

BENEFITS:

  • Automatic and cost saving viscosity measurements with double capillary
  • Strict conformity with standard methods
  • Ultra precise NIR or NTC meniscus detection
  • Standalone operation
  • Multi-instrument network and enhanced operation based on PC with HLIS®

FAST AND ULTRA PRECISE ANALYSES

  • Start your analyses with some clicks and by pressing few buttons
  • Ubbelohde capillary tubes protect sample from external environmental conditions until 2 determinations have been realised in user-defined repeatability limits
  • Dynamic/static sample conditioning quickly reaches the sample equilibrium temperature
  • Highly precise 2 points meniscus detection with near-infrared (NIR), not influenced by surface tension, sample conductivity or water content effects
  • The programmable multi-solvent cleaning cycles clean, wash and dry tubes according to user's preferences
  • Immediately displayed results on local digital screen; they can be directed to an optional printer or a computer system automatically or on demand

ROBUST AND RELIABLE OPERATION

  • Supports intensive operation
  • Fast tube replacements in less than 2 minutes minimise downtimes for routine maintenance
  • Selling and maintenance services by experts from PAC's worldwide network of authorized factory-trained representatives
  • Construction quality and reliable operation supported by a limited warranty on parts and service
  • Customers training at your place or at our facility

CONVENIENCE PC MANAGED WITH HLIS®

  • Controls and monitors up to 16 HLIS-compatible viscometers from a single computer, allowing a fast display of operating status and measurement values
  • Integrated system calibration, auto-test and diagnostics
  • A sophisticated data management based on Windows organizes test parameters, capillaries and results, for an easy recovery
