Automated low temperature viscosity determinations of aviation turbine fuels; high & low temperature lubricant testing
Herzog's HVU 482 Low Temperature Viscometer is ideal for low temperature viscosity testing of aviation turbine fuels and for high and low temperature lubricant testing while meeting or exceeding the requirements of ASTM D 445. 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(tm) 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.
Totally microprocessor controlled, this time-saving instrument features two Ubbelohde-style capillary tubes in a programmable constant-temperature bath, local keypad and display, near-infrared or thermistor timing of efflux flow, and an automatic tube cleaning system.
