DV-79+PRO Digital Viscometer

DV-79+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 levels of shear rate stepless setting. 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-subdivision 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 as options. ◆ 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, ensuring testing standards align with international norms. ◆◆Technical Specifications ◆ Measurement Range: 0.5 mPa·s to 6,000,000 mPa·s (LV series rotors). ◆ Measurement Error: ±1% (F.S). ◆ Rotational Speed: 0.1–750 r/min, stepless speed regulation (gearless drive). ◆ Rotor Specifications: 3 types (C, D, E rotors) or 2 types (A, B rotors). ◆ Power Supply: 110V/220V and 50Hz/60Hz. ◆◆Optional Accessories ◆ Micro-printer, constant temperature water bath, remote controller, standard oil, DV data acquisition, and programmable analysis software.
