Pensky-Martens flash point tester: PMA 5

The automatic Pensky-Martens closed-cup tester measures the flash point at the lowest temperature at which the application of an ignition source causes the vapors of a sample to ignite.
PMA 5 is suitable for flammability applications on both biodiesel and biodiesel-blended fuels along with distillate fuels like diesel, heating oil, and kerosene. It is also commonly used for other potentially flammable liquids.
