Automatic viscometer AVS® 470

capillarylaboratory

The AVS® 470 is a viscosity measuring device for capillary viscometers which does not require an additional PC. The article contains the basic system, equipped with one ViscoPump III for one measuring position, a measuring stand AVS®/SK, a thermostat bath CT 72/2 and a cooler CK 310. But no viscometer. The AVS®470 (opt) is equipped with a ViscoPump III, VZ 8561 for detection of liquid meniscus by IR light barriers. In case of opaque (non-transparent) samples, there is the alternative AVS® 370 (TC), part no. 285415708. In this device, the liquid detection is carried out by thermo-electric (TC) sensors. According to the application, the AVS ®370 can pump the sample liquid by “suction” or “pressure” mode into the measuring bulb of the viscometer. A suitable pneumatic tube set for connecting the viscometer is chosen accordingly. The ViscoSystem® AVS® 470 works according to the glass capillary method – the most accurate method for physically determining the viscosity of Newtonian liquids. The new feature: measurements under vacuum and under pressure with a single instrument, independent of a PC! The ViscoSystem® AVS® 470 permits both working methods. In this way the measuring method is very easy to adapt to the requirements of the application. This also reduces the setting-up time, as both methods are permanently available. Perfectly equipped for fully automatic viscosity measurement
