Rheometers are usually much more imprecise measurement devices. Ubbelohde on the Engler viscometer has led to the adoption of the formula Z.

#UBBELOHDE VISCOSITY METER MANUAL#

SI Analytics Manual Ubbelohde Viscometer includes ring marks. Available with single or dual solvent cleaning, the instrument measures kinematic viscosity in Newtonian fluids like lubricants, fuels or dissolved plastics between 0.15 and 25,000 mm 2 /s. The health and beauty industry does testing of toothpaste so as to not be so thick it will not come out of the tube, but not too thin that it will run out of the tube.Īny industry where consistency matters has a need for viscosity testing. Intrinsic viscosity determinations require precisions of measurement of relative viscosity of about 1 part per thousand or better. Obtained from values given in Tabellen zum Englerschen. Determine absolute and relative kinematic viscosity of liquids with Newtonian flow behavior. The tubes are based on the well-known and proven Ubbelohde design, but only require 8-16 ml of sample and approx. The food and beverage industry tests products like butter and syrups to guarantee batch consistency. The car industry tests the viscosity of oil to ensure that your car engine is well lubricated. (Note: We do offer a #0 rotor that can determine viscosity as low as 0.1 mPa.s, which costs a little extra.) It comes with 4 rotors (#1, #2, #3, #4) and 4 different speeds which allow it to measure any viscosity value in the given range.

#UBBELOHDE VISCOSITY METER PORTABLE#

It is lightweight, easy to use, and portable so you can do your testing right on your production line. The device was developed by the German chemist Leo Ubbelohde (1877-1964).

The advantage of this instrument is that the values obtained are independent of the total volume. It is recommended for higher viscosity cellulosic polymer solutions.

7.2 shows the Ostwald, Ubbelohde, and compact Ubbelohde viscometers. An Ubbelohde type viscometer or suspended-level viscometer is a measuring instrument which uses a capillary based method of measuring viscosity. There is a separate port to connect a printer so you can print your results. The most convenient viscometers for use in measuring intrinsic viscosity are Ubbelohde dilution viscometers 19, 27, 28, 29, although other types such as the Ostwald viscometer are available. This viscometer has microcomputer control technology and comes with a LED screen to evaluate your readings instantly. Depending on the capillary constant and temperature, relative uncertainties of. This is the USS-DVT6 Rotary Viscometer Viscosity Meter w/ LCD Screen which evaluates fluidity and thickness of various fluid materials. Measurement of kinematic viscosity by means of the Ubbelohde viscometer.
