Product Introduction

This instrument is suitable for determining lubricating oil. The principle of operation is to measure the ascending speed of the lubricating oil in the u-shaped tube under constant pressure and prescribed low temperature conditions, expressed as the temperature when the ascending speed under this condition is 10mm/min.
