ISL (PAC)
VH Series    Automatic Houillon Viscometers
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. The method was initially developed for lubricant blending facilities, research labs, and used oil verification measurements. It requires less than 1 milliliter of sample with an average run time of 60 seconds, maintaining the precision of ASTM D 445. Running under custom 32-bit, multi-tasking Windows-based software, you 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. The Model VH 1 integrates a single solvent capacity for tube cleaning, while the Model VH 2 accommodates two solvents, offering more flexibility in solvent selection and more efficient tube cleaning and drying. All VH 2 parts that come in contact with sample or solvents are made of glass, stainless steel and brass, Teflon or Kalrez. Thus, aggressive solvents can be used on this model.
