SNB-3 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, glues, 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 speed settings from 0.1 to 99.9 RPM. Simultaneously displays speed, rotor number, viscosity, torque, 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 SNB data acquisition and graphing software for data collection and analysis, or a micro monochrome printer for timed printing of measurement results. ◆ Optional remote controller for contactless operation, simplifying usage and reducing errors caused by direct contact. ◆ Various standard rotors can be selected as needed. ◆ Optional calibration with standard reference materials from metrology bureaus to align testing standards with international norms. ◆◆Technical Specifications ◆ Measurement range: 100 mPa·s to 80 million mPa·s. ◆ Measurement error: ±1% (F.S.). ◆ Rotational speed: 0.1–99.9 r/min, stepless adjustment (gearless drive). ◆ Rotor specifications: Standard configuration includes rotors #1 to #4. ◆ Measurement mode: Continuous measurement. ◆ Display parameters: Viscosity, rotor number, speed, torque, temperature. ◆ Power supply: 110V/220V and 50Hz/60Hz. ◆◆Optional Accessories ◆ Measurement range: 5–100 mPa·s with additional rotor #0. ◆ Custom rotors available to meet specific customer requirements. ◆ Optional ultra-low viscosity adapter (rotor #0), small sample adapter, micro-printer, constant temperature water bath, remote controller, standard oil, SNB data acquisition, and programmable analysis software. ◆◆Remarks ◆ If the small sample adapter is selected, the standard rotors #1, #2, #3, and #4 will be replaced with rotors #21, #27, #28, and #29. If additional rotors are required, please specify when ordering. ◆ Viscosity measurement range for rotors #1, #2, #3, and #4: 100–80 million mPa·s. ◆ Viscosity measurement range for rotors #21, #27, #28, and #29: 500–10 million mPa·s.
