Gas fume chamber, to determine the burnt gas fume colorfastness of textiles when exposed to atmospheric oxides of nitrogen derived from the combustion of gases.

A specimen of the textile and the test control fabric are exposed simultaneously to oxides of nitrogen from burnt gas fumes until the control shows a change in color corresponding to that of the standard of fading. The change in color of the specimen is assessed with the standard gray scale for assessing change in color.

Includes testing chamber, burning and control chamber, rotating sample rack, standardised gas burner, test duration timer and exhaust port (to be connected to extractor system). Temperature controlled automatically and can be red digitally on the large display.
