VH1 & VH2: Houillon Viscometers


ASTM D7279, ASTM D2270

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
  • Modular design with ultimate configuration flexibility enables up to 16 simultaneous test runs
  • High throughput with complete results in minutes; can complete up to 75 tests per hour
  • Easy constant calibration with reference fluids
  • Reduce waste with small sample size; uses less than 1 ml
  • Multi-instrument networking and PC-based data management
  • Saves calibration parameters for multiple bath temperature settings
  • Automated cleaning system, individually programmable for each tube
