Plastometer PF-12

For Measure Plastic Properties of Coal


  • The PF-12 plastometer is intended for measuring plasticity properties of black coal heated under the conditions defined by the ASTM D 2639 – 08 and ISO 10329 standard. The outcomes of the test are plastometric indicators of the coal.
  • The PF-12 plastometer is a fully automatic, compact, single-furnace instrument. A single furnace with molten solder bath is equipped by sophisticated control system of heating range, heating rate to ensure the required accuracy level to meet the requirements of 6.3 of ASTM D-2639-08, ISO 10329.
  • For quick cooling, the furnace has a built-in fan (allowing another test to be started shortly afterwards).
  • Automatic hammering (per ASTM D-2639-08, ISO 10329 ) system for sample preparation is included
  • Automatic evaluation of the final results form 2 or 3 tests according the standard requirements ASTM D-2639-08, ISO 10329
  • Build – in exhaust device
  • The temperature measurement failure detection
  • Cooling of the furnace by the fan
  • Automatic assessment of each test and the overall result
  • Automatic creation of * csv files for statistical analysis
