Smoke Density Tester

  • ASTM D2843
Smoke Density Tester, accordding to ASTM D2843 Exit Sign Somke Test, is used to measure and describe the relative amount of smoke obscuration produced by burning or decomposition of material, products, or assemblies to heat and flame under controlled conditions.
The test specimen is exposed to flame for 4-minutes, and the resulting smoke is mostly contained in the test chamber. The horizontal absorption was measured across the light beam path of a photoelectric cell, and the condition of the EXIT on the smoke chamber was observed.


  • Standard test chamber, is made from corrosion resistant stainless steel with Teflon coating, to maximize the durability.
  • Equipped with two standard burners to ignite the specimen and drips.
  • The smoke obscuration system consisting of incandescent lamp, silicon photodiode photoelectric detector with cosine calibration function, and light filter.
  • Gas system include the flow meter, pressure meter and pressure reducing valve.
  • Spark ignition and implement timer.
  • Software records light transmission, Max. smoke density(MSD), smoke density grade(SDG), observations.
  • Software processes the data, graph, rating, and export the test results.
