1、 Product Introduction:

The high-precision rotary viscometer LD-WND4 is an instrument used to measure the viscosity of liquids. It determines the viscosity of a liquid by measuring the resistance experienced by rotating components in the liquid. Rotational viscometers are widely used in industries such as chemical, food, pharmaceutical, and petroleum for viscosity measurement in quality control, research and development, and production processes.

2、 Application scope:

Chemical industry: used to measure the viscosity of various chemical solutions, coatings, inks, adhesives, etc.

Food industry: used to measure the viscosity of sauces, honey, dairy products, beverages, etc.

Pharmaceutical industry: used to measure the viscosity of liquid medicine, gel, emulsion, etc.

Petroleum industry: used to measure the viscosity of lubricants, fuels, asphalt, etc.

Research field: Used for viscosity research and material property analysis in the laboratory.

3、 Execution standards:

International standards: ISO 2555, ISO 3219.

National standard: GB/T 10247-2008 "Methods for viscosity measurement".

Industry standards: ASTM D2196, ASTM D2983.
