HVM - 472 - Multirange Viscometer

Test Methods

ASTM D445, ASTM D446, IP 71, ISO 3104, ISO 3105, GOST 33



The Herzog Multi-Range Viscometer (HVM 472) determines direct kinematic viscosity of transparent and opaque liquids fully automated. The easy to operate HVM 472 includes 2 multi-range capillaries with 100 fold measuring range, requires only 18 ml, and delivers precise results. A revolutionary auto sampler offers truly continuous operation, spent sample vials automatically discharge, allowing new samples to be added at any time, even mid-test! For rapid analysis within viscosity range of 0.5 to 600mm2/s, the HVM 472 offers the smart alternative to run samples using 20-fold range Fast Run (FR) capillaries. The HVM 472 shows excellent precision and accuracy in full compliance with ASTM D445.
