Using a "houillon" capillary tube, ISL's VH
Series viscometers automatically determine kinematic viscosity of
lubricating oils, used oils, fuels, polymers and similar materials over
a wide viscosity range.
Initially developed for lubricant blending
facilities, research labs, and used oil verification measurements, today
this method has been approved by ASTM as number D 7279.
ISL’s Models VH 1 and VH 2 each require less
than 1 milliliter of sample, have an average run time of 60 seconds, and
deliver results with the precision of ASTM D 445. Running under custom
32-bit, multi-tasking Windows-based software, users can centrally
monitor of up to 16 capillaries spanning up to 4 baths. Results are
displayed, saved in the database, printed or sent directly to a LIMS
following user-defined protocol.
Model VH 1 viscometer integrates a single
solvent capacity for tube cleaning.
Model VH 2 accommodates two solvents,
offering more flexibility in solvent selection and more efficient tube
cleaning and drying. As all VH 2 parts which come into contact with
sample or solvents are made of glass, stainless steel, brass, Teflon or
Kalrez, aggressive solvents are safe to use.
