VH1 and VH2 - Houillon Viscometer
VH1 and VH2- AUTOMATIC HOUILLON VISCOMETER
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:
In both models, ISL’s custom Windows-based management software enables central monitoring of up to 16 capillaries spanning up to 4 baths. Results are displayed, saved to the database, and printed or sent directly to a LIMS following user-defined protocols. With 40C and 100C bath temperatures programmed, viscosity index can be performed, calculated and printed within minutes.
Houillon Viscosity Method
The term “Houillon” refers to the specific capillary tube used to measure viscosity in ISL’s VH systems. The principle - based on straight flow approach - requires less than 1ml of sample, therefore speeding the warm-up and analysis time. Because the specimen flows through the detection points only once, the houillon method is ideal for both transparent and opaque samples.
