WebPMA 500 is a Pensky-Martens closed-cup flash point tester for determining the flash point according to ASTM D93, EN ISO 2719, and IP 34. It is the first-class solution for automatic high-precision flash point testing in the petroleum, chemical, and fragrance industries, and for test laboratories. There are two basic types of flash point measurement: open cup and closed cup. In open cup devices, the sample is contained in an open cup which is heated and, at intervals, a flame brought over the surface. The measured flash point will actually vary with the height of the flame above the liquid surface and, at sufficient height, the measured flash point temperature will coincide with the fire point. The best-known example is the Cleveland open cup (COC).
