I want to make an inquiry
I want to make an reservation
Explosion Range Tester HWP21-30SE dedicated to testing and evaluating the combustion hazard of gases and flammable vapors, is applicable to measuring the upper flammability limit (UFL) and lower flammability limit (LFL) of gases, vapors or a combustible mixture of vapor and air at standard atmosphere pressure and a set temperature, and the test result can be used as an important reference factor for fire risk assessment.Application Field: chemical industry, pharmaceutical, pesticide, new energy, and scientific research.
Test Standard
The test conforms to test methods of explosion limits of ASTM E681 chemicals (liquids and gases).
Product Features
• Optional round glass test container of 5L and 12L and good compatibility
• Equipped with pressure relief door and spring loaded pressure relief mechanism
