Open Cup Flash Point Tester
Category：Oil Testing Equipment
Introduction
The Open Cup Flash Point Tester is designed to automatically determine the flash point and fire point of petroleum products (excluding crude oil and petroleum fuels) with fire points above 80 °C. By combining automated control with a user-friendly interface, the instrument enables precise, repeatable testing and allows comparison with manual test results. This tester is widely used in quality control, research, and safety verification in petrochemical and industrial laboratories.
Applications
This instrument is suitable for testing the flash and fire points of:
Gasoline, kerosene, diesel, and other refined petroleum products
Lubricating oils
Fuel oils and blended petroleum products
Industrial petroleum-based chemicals
Laboratory quality control of petroleum products
Safety evaluation in production, transport, and storage
