I. Product Introduction

The rotary viscometer is a precision instrument for measuring liquid viscosity. It determines the viscosity of a liquid by measuring the resistance encountered by a rotating component within the liquid. Rotary viscometers are widely used in the chemical, food, pharmaceutical and petroleum industries for viscosity measurement in quality control, research and development, and production.

II. Application Range

Chemical industry: measurement of the viscosity of various chemical solutions, coatings, inks, adhesives, etc.

Food industry: measurement of the viscosity of sauces, honey, dairy products, beverages, etc.

Pharmaceutical industry: measurement of the viscosity of liquid medicines, gels, emulsions, etc.

Petroleum industry: measurement of the viscosity of lubricating oils, fuels, asphalt, etc.

Scientific research: viscosity research and material property analysis in the laboratory.

III. Executive Standards

1. GB/T 10247-2008 "Methods for viscosity measurement"

2. JJG 1002-2005 Verification regulation for rotational viscometers

3. GB/T 15357-2014 Surface active agents and detergents - Determination of viscosity and flow properties of liquid products using a rotational viscometer

4. ASTM D2196-2018 Standard test methods for rheological properties of non-Newtonian materials by rotational viscometer

5. ASTM D2983-17/20/21 Standard test method for low-temperature viscosity of automatic transmission fluids, hydraulic fluids and lubricants using a rotational viscometer

6. ISO/IEC 17025:2017 General requirements for the competence of testing and calibration laboratories

7. ISO 2555:2018 Plastics - Resins in the liquid state or as emulsions or dispersions - Determination of apparent viscosity by a single-cylinder rotational viscometer

IV. Features

15-inch HD LCD color touch screenclear display and convenient operation.
2Formula storageverified test protocols can be systematically archived, supporting quick reuse and team collaboration.
3Stepless speed regulationclearer data and more definite analysis.
4Mechanical transmissionlifting is realized through a manual rocker arm, featuring low noise and strong portability.
