Pensky-Martens Closed Cup Flash Tester

The Pensky-Martens Closed Cup Flash Tester determines flash points of a wide range of products by a closed cup method with two option speed stirring of the sample. The method is extensively used in shipping and safety regulations for detection of contamination by volatile and flammable materials in fuel oils and lubricating oils, and for characterization of hazardous waste samples.


The operating cover mechanism slides the shutter open and applies the test flame at the turn of a knob.  The electrically heated model is equipped with a 1000W nickel-chromium heater with stepless variable control for accurate, repeatable temperature ramps. The heater unit is enclosed in a stainless-steel housing with cooling vents. Includes line cord receptacle and switch for the optional slow speed stirrer. The gas heated model has a built-in nickel plated brass natural gas burner or can be supplied with an artificial gas burner or liquid propane burner. Both models are mounted on a sturdy cast iron base.
