SNB-1 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 speed settings from 1 to 60 RPM. Synchronously 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-subdivision stepper motor drive and a digital LCD with blue backlight. ◆ Optional SNB data acquisition and graphing software for data collection and analysis, as well as an optional micro monochrome printer for timed printing of measurement results. ◆ Optional remote controller for contactless operation of the viscometer, making operation simpler and more convenient while reducing errors caused by contact. ◆ Various standard rotors are available as needed. ◆ Optional standard reference materials from metrology bureaus for calibrating the viscometer, ensuring testing standards align with international norms. ◆◆Technical Specifications ◆ Measurement range: 10 mPa·s to 600,000 mPa·s. ◆ Measurement error: ±1% (F.S). ◆ Rotational speed: 1–60 r/min, stepless speed regulation (gearless drive). ◆ Rotor specifications: Standard configuration includes rotors #1 to #4. ◆ Measurement mode: Continuous measurement. ◆ Display parameters: Viscosity, rotor number, rotational speed, torque, temperature. ◆ Power supply: 110V/220V and 50Hz/60Hz. ◆◆Optional Accessories ◆ Measurement range: 1–10 mPa·s, with additional rotor #0. ◆ Special specification rotors available to meet diverse customer needs. ◆ 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: 10–600,000 mPa·s. ◆ Viscosity measurement range for rotors #21, #27, #28, and #29: 10–100,000 mPa·s.
