Multiphase High - temperature and High - pressure Explosion Limit Tester

The Multiphase High-Temperature and High-Pressure Explosion Limit Tester is an instrument developed based on standards such as EN 1839, ASTM E918, ASTM E2079, EN 15967, and UL9540A to test combustion and explosion characteristics. This instrument can test combustion and explosion characteristics such as explosion limits, limiting oxygen concentration, explosion pressure, and pressure rise rate.

Applications

1. Petrochemical Industry: Explosion risk assessment of fuels, solvents, and multiphase chemical raw materials

2. New Energy Storage: Thermal runaway/explosion risk detection of battery-related multiphase materials (compliant with UL 9540A standard)

3. Chemical Industry: Safety characteristic (explosion/flammability limits) testing of various multiphase chemicals

4. Materials Science: Flammability/explosion limits determination of multiphase materials under high temperature and high pressure environments
