DV-3+PRO Digital Viscometer ◆◆Applications This instrument is designed to measure the absolute viscosity (dynamic viscosity) of Newtonian liquids and is also suitable for non-Newtonian liquids. It is widely used in industries and research institutions such as resin, rosin, adhesives, pharmaceuticals, glue, cosmetics, oils, paints, as well as universities and colleges. ◆◆Technical Advantages ◆ Can be used as a standalone unit or connected to a micro-printer and computer for data acquisition. ◆ Features user-friendly and personalized design with 7,500 shear rates steplessly adjustable. Simultaneously displays various measurement parameters such as shear stress, shear rate, rotational speed, viscosity, time, and temperature. ◆ Full-scale and multi-range linearity are calibrated via PC interface, with measurement performance and functionality reaching advanced international standards. ◆ Built-in RTD temperature probe for real-time sample temperature monitoring, with an accuracy of 0.1°C and a temperature range of 0-100°C. ◆ Utilizes a 16-bit microcomputer processor for high-resolution stepper motor drive and a digital LCD with blue backlight. ◆ Optional DVLoad software allows custom measurement programs to be downloaded to the instrument for fully automated computer operation. DV data acquisition and programmable analysis software are also available for data collection and analysis. ◆ Optional remote controller enables contactless operation of the viscometer, making operation simpler and more convenient while reducing errors caused by contact-based touch. ◆ Various standard rotors can be selected as needed. ◆ Optional standard reference materials from metrology bureaus can be used to calibrate the viscometer, aligning testing standards with international norms. ◆◆Technical Specifications ◆ Measurement Range: 0.5 mPa·s to 6 million mPa·s (LV series rotor); 20 mPa·s to 40 million mPa·s (RV series rotor); 50 mPa·s to 80 million mPa·s (HA series rotor); 200 mPa·s to 320 million mPa·s (HB series rotor). ◆ Measurement Error: ±1% (F.S); ◆ Rotational Speed: 0.1 to 750 r/min, stepless speed regulation (gearless drive); ◆ Rotor Specifications: Standard configuration includes LV1# to LV4# rotors; ◆ Measurement Mode: Continuous measurement; ◆ Display Parameters: Viscosity, rotor number, rotational speed, range, temperature, torque, shear force/shear stress; ◆ Power Supply: 110V/220V and 50Hz/60Hz. ◆◆Optional Accessories ◆ Measurement Range: 0.5 to 10 mPa·s, with additional UL rotor (LV series rotor); ◆ Special specification rotors available to meet diverse customer needs; ◆ Optional accessories include small sample adapter, micro-printer, constant temperature water bath, remote controller, standard oil, DV data acquisition, and programmable analysis software.
