Smoke Transmittance Meter

The smoke transmittance tester measures the transmittance by illuminating a smoke sample with a light source and detecting the ratio of transmitted light intensity to the initial light intensity. It is used to assess the smoke density generated by material combustion, monitor fire safety performance in the plastics and construction materials industries, and guide product improvements.
Selection
When selecting, consider that the measurement range covers actual smoke concentrations, the accuracy meets standard requirements, and the operation interface is intuitive and easy to maintain. Confirm that the instrument complies with industry testing specifications, has a durable structure suitable for the laboratory environment, and its data output format is compatible with the existing recording system.
