This Automatic ASTM D445 Kinematic Viscometer is widely used to determine the kinematic viscosity and dynamic viscosity of Newtonian liquid petroleum products. The test principle is based on measuring the time required for a fixed volume of liquid to flow through a calibrated glass capillary viscometer under gravity at a constant temperature. The kinematic viscosity value is calculated by multiplying the capillary constant by the flow time at a specific temperature.

It is widely used in power industry, petroleum industry, chemical engineering, railway systems, scientific research institutions, and quality inspection laboratories.

The Automatic Kinematic Viscometer is suitable for viscosity analysis of:

• Transformer oil and insulating oil
• Lubricating oil
• Fuel oil and petroleum products
• Chemical liquid materials
• Other Newtonian fluids

Typical industries include:

• Electrical power testing
• Petroleum refining and transportation
