Automatic Flash Point Tester – Pensky-Martens Closed Cup
Qualitest’s QualiFPT-CC-Auto is a state-of-the-art Automatic Flash Point Tester designed for accurate and repeatable determination of the flash point of petroleum products using the Pensky-Martens closed cup method, fully compliant with ASTM D93.
This advanced instrument provides a safe, reliable, and fully automated solution for labs and industries performing quality control, product classification, and compliance testing for flammable and combustible liquids.

What Is Flash Point Testing?
The flash point of a material is the lowest temperature at which it emits enough vapor to ignite in air in the presence of an ignition source. It is a critical parameter for determining the flammability and safety classification of fuels, oils, solvents, and other volatile substances.
Flash point data is essential for:
- Classifying and labeling hazardous materials
- Ensuring compliance with transport and safety regulations
- Quality assurance in petroleum refining, lubricants, chemicals, and coatings industries
Pensky-Martens Closed Cup Method – ASTM D93
The ASTM D93 standard specifies the Pensky-Martens Closed Cup method for determining the flash point of liquids with a viscosity above 5.5 mm²/s (cSt) at 40°C, or that contain suspended solids or tend to form surface films.
This method is commonly used for:
- Fuel oils (diesel, biodiesel blends)
- Lubricating oils
- Solvents
- Paints and varnishes
- Other viscous or solid-containing liquids
ASTM D93 offers three procedural methods:
- Procedure A: For fuels and liquids with flash points between 40°C and 360°C
- Procedure B: For materials with potential surface films or those prone to forming skin
- Procedure C: For biodiesel blends and other specified fuel mixtures
Our QualiFPT-CC-Auto supports all three procedures with precise temperature control, automatic ignition, and programmable test parameters.
