Product Introduction
This instrument is suitable for measuring lubricating oil. The operating principle is to measure the rising speed of the lubricating oil in the U-shaped tube under the condition of constant pressure and specified low temperature, and express it as the temperature when the rising speed is 10mm/min under this condition.
