Viscosimeters are instruments used to measure the viscosity of fluids. The principle is based on measuring the time it takes for a fluid to pass through a glass capillary of a given length. This classical method has an accuracy of 0.1%. This method is suitable for measuring water and fluids of a certain type. Because it is a measurement that is carried out with the glass instrument, it is subject to the limitations of a manual instrument. However, it remains a valid system always used in the laboratory.
Modern technology has developed digital systems that offer a high level of accuracy. Rotational viscometers have a probe immersed in the fluid to be calculated. The effort the instrument exerts to rotate within the fluid is calculated by a processor that shows the data on the display. These instruments are equipped with calibration systems that facilitate the operator's use.
Viscometers are portable instruments used for fixed measurements but also for mobile measurements. For fixed installations, specific instruments also exist in large sizes. In addition to shear viscosity, there is also elongation viscosity. This can be measured with elongation viscometers. But let us take a closer look at the characteristics of this instrument.
Viscometers are important instruments for determining the resistance and viscosity of fluids, and are mostly used to perform various laboratory analyses. They can be more or less accurate depending on the intended use. Viscosity measurements are in fact various, carried out on the move or on a fixed point. In this case, rotational viscometers will be used, or set on a fixed structure. The size of the viscometer will depend on its future use. Modern technological science tends to implement the functionality and performance of these laboratory tools in order to carry out increasingly precise and accurate tests. Colaver is committed to constantly searching the market for the best instruments to offer its customers. Particular attention is paid to the quality/price ratio as an element always to be taken into account.
As with all laboratory equipment, what is required in a viscometer is precision in measuring resistance or viscosity, functionality and high quality, so that the equipment lasts as long as possible while coming into contact with liquids that can damage it. Because viscometers are generally portable instruments, special technology is required to be accurate despite the various situations in which it may be used. Given the wide choice of viscometers, differentiated according to their principle of operation, prices are also variable, depending also on the size of the viscometer, whether it is a rotational or fixed viscometer.
Viscosimeters are generally hand-held instruments.
Among the viscometers, instruments used to measure the viscosity of a liquid, the rotational viscometer is among the most accurate and precise. It measures the resistance of a liquid by means of a special technology that moves the particles, through a rotary motion, and measures their punctuality and resistance, in a very easy and precise way. The rotational viscometer is the fastest way to measure viscosity, and is one of the latest developments in new technology. It consists of a rotating element, usually spherical or cylindrical in shape, and the speed at which this instrument can reach can be set by the laboratory technician and controlled according to the intended use. The most modern rotational viscometers, to facilitate measurement, have a display that shows the speed of rotation, the viscosity measurement, the amount of fluid inserted and many other data.

The importance and price
Whatever the type of viscometer, its use is very important in many areas, from chemistry to the food industry, scientific research, medicine, industrial and laboratory analysis. The data that can be obtained using this equipment are very important. The possibility of varying the speed in the viscometers makes them ideal for measurements in the industrial environment, where certain data must be monitored by law in order for them to pass the high quality standards checks according to current regulations. In the food industry, too, it is necessary to carry out analyses using viscometers in order to assess the quality of a product, in compliance with regulations. This is why it is essential to use high quality and precise laboratory machinery, to be able to easily carry out the measurements required to produce excellent end products quickly and accurately.
The Ford Cups
Ford Cups are used to determine the hardness of liquids. They are used in industry and research laboratories only for low-viscosity liquids. This is measured on the basis of the flow rate and the time it takes for the liquid to pass through the nozzle from the viscometer.
