QHow do I choose right spindle and speed?ĪStandard VISCO™ comes with three types of spindles. QI'm considering purchasing, can I try it before I buy it? The cone plate type can determine the flow characteristics of non-Newtonian fluids by changing the rotational speed. There are different types of spindles: coaxial double cylinder, single cylindrical, and cone and plate. When a cylindrical spindle is placed in the sample and rotated at a constant speed, the viscosity is determined by measuring the torque (shear stress) acting on the cylindrical surface. The structure is simple, easy to use, and the measurement range is wide and can be measured with high accuracy. Rotational viscometer is one of the most common viscometers used. There are also other measurement methods such as viscosity cups and Line Spread Tests (LST).ĪTAGO's viscosity meter VISCO™ is measured on a principle called rotational viscosity. There are different types viscometers that uses various measurement methods.įor example, in the Japanese Industrial Standard JIS Z 8803, viscometers are classified as follow: Part numberįeel free to order or consult from this form Please contact me. If you would like a standard solution with JCSS calibration certificate, please click here. It is recommended to calibrate with a standard solution that is close to the viscosity of samples being measured. The standard solutions are available in various viscosity. ATAGO's viscometer VISCO™ provides the following standard solutions: If you are considering routine calibration, we recommend that you decide the frequency based on the circumstance in which the instrument is used and past measurement results. Calibration is recommended when the measurement environment has changed drastically or when the measurement results are out of the norm. Calibration is an important task to ensure the reliability of the measurement results. Calibration compares the true value and the value measured from the instrument.
