This unique viscometer is ideal for ink, paint, food, pharmaceutical, chemical processing, rubber, oil, paper, or any viscometry application that requires high accuracy and fast response time. The tuning fork vibration method ensures excellent accuracy and repeatability with a wide range of continuous and real time measurement. The thin, small size of the sensor plate allows even minute changes of viscosity and temperature to be tracked on a real-time basis. Additionally, the design of the sensor plates allows minimal deformation of the sample texture, and thus enables measurement of Non-Newtonian fluids.
Viscosity is measured by detecting the driving electric current necessary to resonate the two sensor plates at constant frequency of 30 Hz and amplitude of less than 1mm. The low drive frequency allows measurement of foam without breaking or scattering the samples. This tuning fork vibration technique also allows the measurment of flowing samples, including liquid turbulent flow, which enables the exact comparison of field and laboratory samples. Sol and gel sample fluid, like starch, can also be measured during the change of material characterisitics.
Included software lets you collect, store, and graph data for analysis. It allows you to monitor any change in sample temperature or viscosity.

The SV-10/SV-10A series of tuning fork vibro viscometers are capable of continuous measurement over a range of viscosities from the extremely low (0.3 mPa·s) to the high (10,000 mPa·s).
These viscometers are able to easily measure the state transition from sol to gel as there is no need to change sensors during measurement.
Measurement intervals can be set freely allowing for continuous 24-hour measurement or measurement of any long term viscosity change.

Gel point: The liquid to solid phase change

Example) Gelatin, agar, glucomannan, thickening stabilizer, hydrogel

Cloud point: Micelle structure change in a surfactant

Example) Paraffin, non-ionic surfactants

Suspension: A dispersion system such as a slurry, sludge or colloid

Example) Cement, butter, milk, cream, asphalt, ink, paint, gold nanocolloids

Lubricant Properties: Change in viscosity accompanying temperature change

Example) Engine oil, grease, mineral oil, synthetic oil, water-based lubricants, animal and plant oils

Rapid Rise in Viscosity: Measurement of the curing point (measurement of adhesives)

Example) Egg white/yolk, solder flux, silicone adhesive, mortar, plaster, rubber and polymer adhesives

Low Viscosity Measurement: Stable measurements around 1.0 mPa·s (viscosity, mouthfeel and sensory tests)

Examples) Food related - Water, alcohol, liquors, soft drinks, soy sauce, milk, Medical related - Blood, protein, drugs, easily swallowed foods, easily digested foods Other solvents - cosmetics, semiconductor polishing agents

High viscosity measurement: Stable measurements up to 100Pa·s

Example) Honey, polymer solutions, toothpaste hand creams, lipstick, chocolate


Excellent functional condition.  Suggested to have annual calibration performed prior to entering service.
