Depending on the capillary constant and temperature, relative uncertainties of. 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. 9999.99 Sĭynamic viscosity, dynamic viscosity, relative viscosity of molecular weight, intrinsic viscosity, viscosity, etc. Measurement of kinematic viscosity by means of the Ubbelohde viscometer. An Ubbelohde type viscometer or suspended-level viscometer is a measuring instrument which uses a capillary based method of measuring viscosity. An example is the slower flow of syrup from a. What Is a Viscometer Viscometers are instruments used to measure viscosity, the internal friction of the layers of a liquid in motion. Supplied calibrated in accordance with ASTM D445- IP71, BS188 and IS03105 and.159. Viscometers or viscosimeters are important to many industries, including the adhesive, biotech, chemical, food, paint, petroleum, and pharmaceutical industries. Measure the viscosity range: 0.35-5000 was/s (related to the specific scope and supporting the viscosity of the tube)ĥ. To ASTM D445-IP71, BS188, ASTM D446 51 562, BS2000 Part 71, ISO3104, ISO3105. Unlike the Cannon-Fenske Routine viscometer, suspended. The bath temperature fluctuations, evenness ℃ : + / - 0.01Ģ. The Ubbelohde viscometer and other suspended-level viscometers are used to measure transparent liquids. The powerful calculation function, containing all the related calculation formula, viscosity can be obtained conveniently characteristic viscosity, viscosity number (more than strong viscosity), viscosity and kinematic viscosity, molecular weight resultġ. Currently the world's most advanced pressure method is used to improve the samples, to avoid the many defects caused by the traditional vacuum method to improve the sampleĤ. Automatic measurement, time saving worry - automatic measuring time, automatic continuous measuring viscosity, automatic data filtering, automatic calculation resultsģ. Constant temperature accurately, to guarantee the viscosity measurement precision and repeatability, thermostatic bath temperature uniformity and volatility are plus or minus 0.01 ℃Ģ. Thus, a rheometer can be considered as a special type of viscometer. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used. Widely used in polyester PET, get togetherĪcrylamide PAM, polyamide fiber, organic silicone, polyurethane, acrylic, polylactic acid, and other areas of the polymeric material.ġ. A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. Model Number IVS300-6 Brand Name YM Payment Terms T/T, paypal Brief introduction:Īccording to the standards such as ISO, ASTM, DIN, GB design, suitable for automatic measurement of ubbelohde viscometer, systemīy the viscosity measurement units, precision constant temperature trough, refrigerator, main controller and software composition, can be calculatedĭynamic viscosity, dynamic viscosity, relative viscosity of molecular weight, intrinsic viscosity, viscosity, etc.
