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 laboratories, and used oil monitoring where small sample size and quick results were required, the ISL VH viscometer offers exceptional performance, providing results in 60 seconds using less than 1 ml of sample.

The VH series of viscometers include:

  • Model VH1: integrates a single solvent capacity for tube cleaning
  • Model VH2: accommodates two solvents, offering added flexibility in solvent selection for efficient tube cleaning and drying and withstands the use of aggressive solvents
