A COMPANY APPLICATIONS: METHODS: ASTM D 445 ASTM D 446 ASTM D 2270 IP 71 Sections 1 & 2 ISO 3104 ISO 3105 Viscosity LIQUID PETROLEUM PRODUCTS AVIATION TURBINE FUELS WATER-CONTAINING EMULSIONS LUBRICANTS USED OILS POLYMERS RESIDUES Automate kinematic viscosity testing while meeting or exceeding ASTM D 445 requirements. Herzog’s HVU Series offers truly stand-alone operation with exceptional bath temperature range and stability. It simultaneously tests up to two samples using standard Ubbelohde-style capillary tubes. Near-infrared (NIR) or NTC thermal meniscus detection systems precisely measure flow properties of even the most challenging sample types, while an automatic tube cleaning system incorporates Kalrez™ seals to withstand use of aggressive solvents such as toluene or acetone. Complete cycle time, including automated cleaning, is 30 to 40 minutes. Results can be exported immediately or on-demand to a printer or LIMS. Add the powerful Herzog Laboratory Information System (HLIS®) Windows-based software for enhanced operation and data management. HVU Series Automated Viscometers ADVANTAGES: Economical, automated dual-capillary viscosity measurements Strict accordance to standard methods Ultra precise NIR or NTC meniscus detection Stand alone operation Multi-instrument networking & enhanced PC-based operation with HLIS HVU 481: 20º to 150ºC (68 to 302ºF) HVU 482: -40º to +100ºC (-40 to +212ºF)
