A brand new small and innovative Viscometer by Atago has just been launched. The VISCO™ features a sleek, modern design, so that it can be used almost anywhere, even in places that don’t have a power source.
The digital interface is easy-to-use, allowing you to select spindle, RPM and beaker settings. USB connectability makes it easy to transfer data to your PC automatically, so you’ll never miss a measurement.
Atago has used their 70+ years of industry experience with visocometers to develop this innovative new portable design that is simple to use. There is no complicated set-up, measurement preparation can easily be done with just one hand and operation requires only one dial button.
Viscosity is a measure of a fluid’s resistance to flow. The measurement describes the friction within a fluid. A higher viscosity indicates a thick flowing liquid, eg honey will have a higher viscosity than blood.
The VISCO™ tests the viscosity of a liquid by measuring the torque (a force that causes rotation) required to rotate a spindle at a speed set by the user.
Viscosity measurements are used in areas such as quality control of foods / beverages and the processing of various products in many industries.
- Beverages – critical parameter in production, eg tomato juice needs to flow through production line in a constant, homogenised state
- Dairy – viscosity can vary according to fat content, pH and pasteurisation
- Sauces – important measure for consistency in sauces
- Olive oil – Newtonian fluid *
- Jam – important factor in making jam spreadable
- Toothpaste – the right viscosity will allow the toothpaste to break cleanly from the tube and retain its shape without flattening
- Cosmetics – a smooth, light, easily spreadable quality is desirable
- Adhesives – properties such as bond strength, smoothness and ease of flow are assessed through viscosity measurements
- Paper – starch
- Resins, polymers, paints, varnishes, sodium silicate, etc – viscosity is important for flow and smoothness
- Fluids, lubricants and slurries – viscosity affects wear and tear of machinery. Low viscosity is often necessary for circulation and to ensure precision when spraying or coating
* A Newtonian fluid does not change its viscosity even when force is applied, eg the viscosity of honey is not affected by force, such as squeezing the bottle, or speed. Only temperature can cause a change in viscosity.
