Viscometer classification

1. Rotary viscometer

The rotary viscometer measures viscosity by measuring the adhesion resistance of viscous substances on a rotating body, and is suitable for testing low viscosity liquids such as water and alcohol.

2. Tube viscometer

The tube viscometer calculates viscosity by measuring the flow resistance of viscous substances in pipelines, and is suitable for testing high viscosity liquids and semi-solid materials.

3. Oscillating viscometer

The oscillating viscometer calculates viscosity by measuring the adhesion force and flow velocity of the test substance in an oscillating state, and is suitable for testing high viscosity liquids and semi-solid materials.

Selection precautions

1. Type of test substance

Different types of viscometers are suitable for different types of test substances, such as rotary viscometers for testing low viscosity liquids, and tubular viscometers for testing high viscosity liquids and semi-solid materials.

2. Testing scope

The testing range of a viscometer refers to the minimum and maximum viscosity it can measure. When selecting a viscometer, the appropriate viscometer should be selected based on the viscosity range of the substance to be tested.

3. Accuracy and repeatability

Accuracy and repeatability are two important indicators for evaluating the performance of a viscometer. When selecting a viscosity timer, attention should be paid to its accuracy and repeatability to ensure the reliability of the test results.

4. Convenience of use

The convenience of using a viscometer is also a factor to consider when choosing. The operational simplicity, reading accuracy, and maintenance difficulty of the viscometer should be considered.

5. Price and Brand

Price and brand are also factors to consider when choosing a viscosity timer. The appropriate brand and price of viscometer should be selected based on budget and needs.

Summary

Through this article, we have learned about the classification and selection considerations of viscometers. When choosing a viscometer, factors such as the type of test substance, testing range, accuracy and repeatability, ease of use, price, and brand should be considered, and a viscometer that is suitable for oneself should be selected to ensure the accuracy and reliability of the test results.
