Product Description

Product Introduction

This viscometer adopts high‑performance imported micro‑computer chip, imported stepping motor and other key components. It features a 5‑inch touch‑screen for display and operation, supporting program setting, automatic control, timed measurement, automatic scanning and other functions. It is capable of measuring the absolute viscosity of Newtonian liquids or the apparent viscosity of non‑Newtonian liquids. The instrument delivers high sensitivity, high accuracy, reliable test data and excellent repeatability.

Machine Functional Features

1. 5‑inch touch‑screen for operation and display. User‑friendly interface with abundant displayed information and powerful human‑machine interaction.
2. Micro‑computer drive technology with imported stepping motor ensures accurate, stable and reliable rotation speed.
3. Anti‑static housing and metal lifting rod. Newly‑designed shaft tip guarantees long‑term service life.
4. Stores up to 30 sets of test data and test conditions.
5. Timed‑measurement function, ideal for testing non‑Newtonian liquids.
6. Automatic conversion between dynamic viscosity and kinematic viscosity (density of sample must be input).
7. Automatic scan function: the instrument automatically recommends suitable rotor‑speed combinations.
8. Automatically shows the test range for selected rotor and speed; triggers auto‑alarm when measurement exceeds range.
9. Equipped with print interface for direct connection to micro‑printer (printer sold separately).
10. 0.1‑200 rpm continuously variable speed, convenient for rheological property analysis. Test data can be exported via USB flash drive.
11. Multiple optional accessories available to satisfy diverse measurement requirements: PT100 temperature sensor, ULR ultra‑low viscosity adapter, SSR small‑sample adapter, thermostatic bath, printer, DVT upper‑computer software, viscosity standard solutions.

Rotor configuration notes

• LV standard rotors (1#, 2#, 3#, 4#): for low‑viscosity sample testing

• RV/HA/HB standard rotors (R2, R3, R4, R5, R6, R7): for high‑viscosity sample testing
