AT875 Smoke Density Tester

is widely used in many industries, such as plastics, rubber, textile covering, paint, wood and other materials. The measuring principle of this instrument is Lambert-Beer's law. The smoke density is expressed by the fraction of the transmittance of smoke in the initial transmittance measured by the optical system, and the maximum specific optical density is calculated by the minimum percentage of the transmittance. The detection indexes are mass optical density MOD, optical density OD and specific optical density Ds. In addition, other analytical instruments, such as gas detection tube, ion chromatography, liquid chromatography, etc., can be equipped for qualitative and quantitative analysis of tobacco toxicity.

★ The diameter of the beam is 51 mm, the computer records the specific optical density automatically according to the change of light

★ The weight change of the test sample is automatically collected and recorded by computer

★ Computer automatic control, acquisition, recording and result calculation

★ Lower aperture has annular heater, so that the temperature on the light window is between 50 and 55 ℃, which can reduce the smoke concentration on the surface to the lowest level.
