Droplet Test Instrument for Grease with wide Temperature Range

This instrument is designed and manufactured in accordance with the requirements specified in the National Standard GB/T3498 of the People's Republic of China, "Determination of Drop Point of Grease in a Wide Temperature Range". As a metal bath apparatus, it is suitable for determining the drop point of grease according to the provisions of GB/T3498.

The testing procedure involves placing the grease into a specialized grease cup equipped with a drop point thermometer. Under specified heating conditions, the temperature at which the first drop of liquid from the sample in the grease cup occurs is defined as the drop point.

The SL-OA98 Droplet Test Instrument determines the drop point of grease at elevated temperatures using a metal bath apparatus in accordance with GB/T 3498.

Primary Applications:

1. High-temperature grease drop point determination – Measuring the temperature at which the first drop of liquid from a grease sample occurs under specified heating conditions
2. High-performance grease evaluation – Testing greases designed for extreme temperature applications
3. Automotive and industrial lubricant quality control – Verifying high-temperature performance of greases
4. R&D and product formulation – Developing greases with enhanced thermal stability
5. Third-party testing laboratories – Providing drop point analysis for high-temperature grease applications
