An exceptional time and cost saving instrument, the Petrotest® PMA-4 is the first and only 12-position Pensky-Martens flashpoint tester (single position shown). Featuring ASTM D93 (A&B), Search, Rapid, and user-customized test programs, the compact design enables the complete PMA-4 (with Autosampler-see below photo) to be set up on the benchtop or in most lab fume hoods.
