Product Name: Model HTD13285 Dual Display Twelve-Speed Digital Rotational Viscometer for Calculating the Viscosity of Pseudo-plastic fluids Model NO.: HTD13285 Viscometer Type: Rotary Material: Aluminum, Iron, Copper, Stainless Steel, Engineeri Trademark: haitongda Transport Package: Aluminum and Plastic Box Then Carton Specification: 560*425*265mm Origin: China HS Code: 9027809900 Product Description 1,Introduction Model HTD13285 Digitalrotationalviscometer is atype of viscosimeter newly designed by our company.The viscometer is designed with embedded configuration,It is equipped with ahigh-precision Angle sensor, driven by astepper motor, and the speed is more stable and accurate;The buttons on the panel are easy to operate,High resolution LCD screen can display the float rotation Angle and stirring speed in real time.This product can be widely used in petroleum, chemical, food, medicine, cosmetics and other industries.The introduction of the working principle:Put the slurry cup filled with liquid on the tray,The liquid enters the annular space (shear gap) formed between the external outer sleeve and the floater of the viscometer. When the motor drives the outer sleeve to rotate,The outer sleeve in the liquid is subject to the force applied back to viscous resistance,the force can produce torque to the floater in the outer sleeve through the liquid under test in the annular space. The floater is attached to the Angle sensor,when the torque is balanced with the viscousresistance,the Angle sensor will detect the Angle of floater rotation. Due to the Angle of the floater rotation is directly proportional to the viscous resistance of the outer sleeve,the sensor's Angle value is multiplied by aspecific coefficient to get the final viscosity,and the Angle value of the sensor is also displayed on the LCD screen for reading. The shear rate and viscosity have alinear relationship,in other words, the relation between shear stress and shear rate is astraight line. In practice, many fluids do not follow the Newton's law. But its rheology is closer to Newton's law, so that it can be measured by aviscometer and the test result will be more accurate. Thecalibration mode of the Model HTD13285DigitalRotational Viscometer is Linear calibration of the Newton mode, Which is not suitable for the samples do not conform to the Newton linear calculation method.In this case, the measurement of the viscosity and the calculation of the velocity should use theNonlinear computing methods. When the instrument operates at the rate of 300r/min,The measurement unit of the viscometer iscPormPa.s. The data measured at other speeds can be converted. The sixth part of this paper presents amethod for calculating the viscosity of pseudo-plastic fluids,such as drilling fluids.When different rotating speeds are selected or different combinations of torsional spring and float are used,the optional range of shear rate may change. To widen the shear stress's range and test more fluids,it can be solved by replacing different kinds of torsion springs.2,Type SpecificationModelNameHTD13285Digital rotational viscometer3,Technical SpecificationNo.Technical Specification1Power supply100V-240V 50HzWith 24VDC 5A power adapter2Motor power40W3Speed range0.9,1.8,3,6,30,60,90,100,180,200,300,600r/min4Measuring accuracy1~25 mPa·s ±1 mPa·s(Newtonian fluid)25 mPa·s above±4% (Newtonian fluid)5Viscosity measuring rangeNewtonian fluid: 0~300mPa.s (F1 Measure component ) 0~60mPa.s (F0.2 Measure component )Non-Newtonian fluid:0~150 mPa.s (F1 Measure component ) 0~30 mPa.s (F0.2 Measure component )Shear stress: 0~153.3Pa (F1 Measure component ) 0~30.7Pa (F0.2 Measure component )6Net weight /Gross weight7.24kg/9.1kg7Overall dimensions310×200×470mm8Packing size560×425×265mmHOT SALE:Certification:Team:Workshop:Warehouse and transportation:FAQ:Q1 :Are you amanufacturer or atrading company ?A1: We are manufacturer.Q2: What is your main brand?A2: Our brand is Haitongda, which is famous in China and other nation.
