Capillary viscometry from SI Analytics – know-how from the very beginning Innovative capillary viscometry – Further developments and improve- 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 instru-ments and accessories led to a...

ViscoCIock. If you need more accuracy: The ViscoClock is the economically priced introductory model in the field of automatic viscosity measurements. Manual measurements with a stopwatch and a trained eye is something of the past because time is money. The ViscoCIock The ViscoClock is an electronic time-measuring unit used to determine abso-lute and relative viscosity. It consists of a stand which is used to mount a viscometer and the electronic measuring unit. The two measuring levels are integrated in the stand made of high-quality PPA synthetic material, and the electronic measuring unit...

AVS® 470 - Precise and Reliable ^ Working with the AVS® 470 is easy The desired measurement method can be preselected and started on the device. The entire measurement is automatic to eliminate subjective measurement errors. Once the set pre-heating time is reached, the desired number of mea- surements are taken and the viscometer automatically cleaned if required.The status of the measurements is con- tinuously displayed. If required, individual parameters may be input via an included PS 2 keyboard. A serial printer can be used to print measurement logs. The connections are on the front...

Technical data Clear user guidance, clear status - even without PC! UiscoPunp Check After switching on the AVS® 470 a self test is run and then an entry prompt appears. The parameters can be set in the test mode. The t0 value is determined automatically. punp power: All setup parameters can be preset conveniently e.g. pressure/suction, velocity waiting time between two tests, etc. result, carr-. stand. dev,= The readings can be read off conveniently on the display regardless of whether or not Measuring range (time) up to 9,999.99 s; resolution 0.01 s Measuring range (viscosity)pressure:...
