The new Sine-wave Vibro Viscometer, the SV-A Series, is a solution to the excessive use of expensive sample fluids during viscosity measurements. This new viscometer can perform viscosity measurements with sample liquid as small as 2ml (SV-1A).
The SV-A Series incorporates the tuning-fork vibration method. Unlike a rotational viscometer, which requires several different rotors to cover a wide range of measurements, the tuning-fork vibration viscometer is capable of using the same, fixed sensor plates to perform continuous measurements from very low to high viscosity [SV-1A: 0.3~1000mPa•s (cP), SV-10A: 0.3~10000mPa•s (cP), SV-100A: 1000~100000mPa•s (cP)].
The SV-A Series has a temperature sensor (0 ~ 160˚C) right next to the viscosity sensor plates: it is widely known that viscosity is temperature dependent (−2 ~ −10%/˚C) and this feature enables users to easily monitor the relationship between viscosity and temperature. In addition, the SV-A Series also comes standard with the Windows Communication Tools, WinCT-Viscosity that receives viscosity and temperature data from the SV-A Series and creates a graph on a PC in real time. Consequently, changes in viscosity and temperature over time as well as the correlation between viscosity and temperature can be observed visually.
Furthermore, the SV-A Series features a super-fast measurement speed (the initial viscosity coefficient is indicated just 15 seconds after starting the measurement), very high accuracy (repeatability is only 1% of the reading), and a simplified calibration function (a one-key operation that utilizes purified water), etc.
Please see the Users Handbook for the SV Series for further details.

The AVSPro automatic sampler is a fully automated measuring instrument for determining the viscosity of Newtonian fluids with capillary viscometers.
In spite of the high sample throughput, the AVSPro provides maximum accuracy and reproducibility and even allows unsupervised 24-hour operation.
The AVSPro automatic sampler works with the capillary method, which is the most precise method for determining the viscosity of Newtonian liquids in terms of physical chemistry. The great versatility offered by viscometers with optical and TC sensing systems opens up an extremely wide range of applications. This includes measurements of clear liquids as well as opaque petroleum products.
The main feature of the automatic unit is the three-axis positioning mechanism of the sample dosing system. The new X-Y-Z positioning mechanism allows parallel operation of up to eight viscometers in two thermostatic baths, which can be set at two different measurement temperatures.
Because of its large throughput capacity and its functional reliability, which it has demonstrated in the course of continuous practical operations, the AVSPro has proven itself to be an indispensable instrument for day-today utilization, particularly in the petroleum and plastics industries.

The viscosity of Newtonian fluids can be most precisely determined using capillary viscometers. This method of measurement, measures the time taken for a defined quantity of fluid to flow through a capillary with a known diameter and known length. With the industrial production of such precisely calibrated capillary viscometers, we have created the conditions to enable this measuring method to establish itself worldwide as a reliable procedure.
With the development of the first automatic measuring systems, we replaced the stopwatch with automatic registration of the fluid at the start of the 1970’s. Since then, subjective measuring errors have been a thing of the past.

New: For the first time ever, you can use the same device to work with “pressure“ or “suction“. This gives you more flexibility and better adjustment to the liquids to be examined.
The ViscoSystem ® AVS 470 is a measuring system that includes everything you need to take precise and reproducible measurements without a PC. All common types of viscosity calculation are integrated into the device, a small PS2 keyboard is all you need to enter additional data. A serial printer can be used to document your measuring results. Virtually all customary capillary viscometers can be used.
With the ViscoSystem® AVS 370 you are perfectly equipped for all tasks involved in determining viscosity. PC-controlled, the AVS 370 determines the time which the liquid to be examined requires to flow through the measuring distance in the capillary viscometer. Measurement of the flow time of the liquid’s meniscus can be scanned optoelectronically or with TC sensors thus enabling viscosity measurement of clear fluids through to black or fully opaque liquids. If necessary, the system can be extended to form a multiple measuring station with PC-controlled multi-tasking. The WinVisco 370 software enables parallel operation of two fully equipped AVS 370, with a total of eight ViscoPump II modules.
