A flash point apparatus is a laboratory instrument used to find the lowest temperature at which a liquid gives off enough vapor to ignite when exposed to a flame or spark. It tests fuels, lubricants, and solvents to ensure safe storage and transport.
Main Types of Testers
- Closed-Cup Testers: Contain the sample vapor in a closed chamber for precise, lower temperature readings (e.g., Pensky-Martens or Abel apparatus). Best for volatile fuels.
- Open-Cup Testers: Expose the sample to the open air during heating (e.g., Cleveland Open Cup). Best for high-temperature lubricants and asphalt.
