Building Material Fire Tester Building materials smoke density testing machine is suitable for building materials and its products and other materials burning static smoke volume measurement.

Building Material Fire Tester Characteristic:
The instrument is controlled by computer and consists of combustion system, photoelectric system and display and print system.
The computer automatically recorded three parallel tests, calculated the average value of smoke density measured every 15s, and summarized the integral curve of smoke density and test time, and printed the test report.
Automatic timing, automatic ignition, automatic smoke exhaust;
For the maximum smoke density (MSD) and smoke density grade (SDR) of the specimen :0-100% continuous measurement, automatic calculation and printing test results;
The correction error of standard filter is not more than 3%.
The Bunsen burner applied flame to the sample for 4min;
