Pensky Martens Flash Point Tester PM4

Pensky-Martens Flash Point Tester – PM4

The semi-automatic Pensky-Martens closed cup tester measures the flash point at the lowest temperature at which the application of an ignition source causes the vapours of a sample to ignite. PM is suitable for flammability applications on diesel, heating oil, kerosene and other potentially flammable liquids.



The patented One-Twist head guarantees the safe and easy one-hand connection of the shutter release and stirrer.

  • The two ignition systems in each unit give you the flexibility to work with electric or gas igniters: If the gas ignition is used, the electric igniter will automatically relight the gas flame during the test, if necessary.

Convenient Operation

  • The preset stirrer speed comes in handy when you have to choose between the methods A (120 rpm) and B (250 rpm).
  • The stirrer will be stopped automatically during the dipping process but can also be switched off manually.

Customized User Flexibility

  • The stainless steel test insert PM-NIRO (optional) is an alternative to the standard type made of brass. It was developed for applications with aggressive samples, for example.
  • Digital precision barometer (optional) with a measuring range of 300 mbar to 1100 mbar and certificates for 5 or 10 measuring points.
  • Digital thermometer (optional) with a measuring range of up to 400 °C: a convenient alternative to glass thermometers
  • Thermometers in °F (optional)
  • Draft deflector (optional)
  • Tray (optional) designed to hold cup/lid, thermometer and igniter when they are out of use
