DV-2+PRO Digital Viscometer

DV-2+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 stepless setting of 1,000 shear rates. 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 microprocessor for high-subdivision stepper motor drive and a digital LCD with blue backlight. ◆ Optional DVLoad software allows custom measurement programs to be downloaded for fully automated computer operation. DV data acquisition and programmable analysis software are also available. ◆ Optional remote controller enables contactless operation of the viscometer, making it more convenient and reducing errors caused by contact-based touch. ◆ Various standard rotors are available 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 rotors); 100 mPa·s to 40 million mPa·s (RV series rotors); 200 mPa·s to 80 million mPa·s (HA series rotors); 800 mPa·s to 320 million mPa·s (HB series rotors); ◆ Measurement Error: ±1% (F.S.); ◆ Rotational Speed: 0.1 to 200 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 rotors); ◆ Special specification rotors are available to meet diverse customer needs; ◆ Optional accessories include small sample adapter, micro-printer, constant temperature water bath, remote controller, standard oil, and DV data acquisition and programmable analysis software.
