Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to an oil smoke point meter. Background Technology

[0002] Smoke point refers to the temperature at which smoke is observed when an oil sample is heated under unventilated conditions. It is generally detected using an oil smoke point meter. During the test, the tester visually observes whether smoke is produced during the heating of the oil. After seeing the smoke, the temperature displayed on the screen is checked to complete the measurement. For this purpose, an LED light is usually installed in the smoke point meter to illuminate the heated area, making it easier to observe the smoke. However, most smoke point meters have fixed LED lights, which are not easy to adjust. Therefore, only the positions of the electric furnace and the oil sample can be adjusted, which greatly affects the efficiency of the experiment and is inconvenient. Utility Model Content
