The Viscolite® VL7 is an easy-to-use portableinstrument for the instant measurement of viscosityanywhere at any time using a simple dip-in probe. Noprior setting-up or adjustment is required.The sensor is a solid probe with no moving parts, sealsor bearings. It is connected by a coiled flexible cableto a display unit powered by four AA batteries. Theprobe also incorporates an integral platinum resistancethermometer (PRT). The whole system is supplied in acompact carrying case for ease of transport.The Viscolite can be used with any volume of fluid,from a cupful to a tank. Readings are made instantly,enabling rapid assessment of samples or batches in situ.The solid sensor can be wiped clean in moments.This combination of toughness, f lexibilit y andportability make the Viscolite the ideal instrument forthe spot measurement of viscosity at a remote site, inthe laboratory or in a busy factory.

The Unique Hydramotion Viscolite 700
- Fast, accurate & robust
- World’s only truly portable viscosity meter
- Solid 316 stainless steel probe

The solid stainless-steel sensor is simply immersed into the fluid to obtain an immediate viscosity measurement. There is no limit on vessel size or fluid volume, so long as most of the probe is covered. Simply wipe clean after use.
- Digital Precision in an Instant
Measurements are shown instantly on a digital display. The lightweight readout unit and probe, combined with long battery life, make the Hydramotion Viscolite hand-held viscometer well suited to long duty in the factory or laboratory or on the move.
The Viscolite is amazingly robust - able to withstand the most heavy-handed use without sacrificing outstanding accuracy and sensitivity. You can even stir the fluid with it! Furthermore, the absence of any moving parts, seals or bearings means maintenance is virtually eliminated. All Viscolites are factory calibrated in a ISO9001 laboratory and come complete with their own carrying case, User Manual, and Calibration Certificate. A standard feature is integral temperature measurement for automatic temperature correction of viscosity.
- Making waves in sensor technology
The Viscolite viscometer is in a class of instruments called vibrational or resonant viscometers. Vibrational viscometers work by creating waves — but it turns out that the type of wave is very important. Not just any wave will do.

- Viscosity is a shear measurement. It can only be truly assessed under shear conditions, so we use shear waves.There are many other types of vibrational waves but these are avoided as they can behave unpredictably in process environments.
- To the naked eye, nothing moves. The solid stainless steel sensor is submerged in the fluid and made to move back and forth microscopically at a high frequency. This is called “resonance”. As the surface of the sensor shears through the liquid, energy is lost to the fluid because of its viscosity.

The dissipated energy is accurately measured by microprocessor-controlled electronics and then equated back to viscosity. Higher viscosity causes a greater loss of energy and hence a higher reading.
The harnessing of the wave dissipation principle with solid engineering design gives Hydramotion viscometers a rare combination of incredible sensitivity and toughness.
