The CMT Flash Point Tester is a device that can measure the temperature at which a material ignites in air using a closed cup method and only 2 ml of sample. The flash point of engine oils can indicate if there is fuel contamination, which can cause severe damage to the engine. The flash point of a material also affects how it is classified, stored, and transported, according to safety regulations.

The Flash Point Tester is a compact, bench top / portable, closed cup instrument that can perform ‘flash / no flash’ tests or determine flash point values up to 300°C using either Ramp or Rapid Equilibrium methods. The operating principle is that a cup containing the sample to be tested is electrically heated in a ramp function to automatically increase the temperature for repeated tests until a flash is observed or the end of the search range is reached, allowing rapid determination of samples.
