VH1 & VH2 Houillon Viscometer for ASTM D7279 & 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.
