3 Metre Cube Smoke Density Tester

None halogen cables and materials are required to measure smoke density; the main principles of the smoke density is measured in a particular space, cable or material in a particular combustion or radiation condition, which will produce smoke, the light beam will decay after passing through the smoke,so the light density and smoke density can be calculated by measuring the light transmittance.

TESTECH Wire and Cable Smoke Density Tester comply with  IEC61034-1 ~ 2: 1997"Measurement of smoke density of cables and optical cables under specified conditions".It is used for the measuring power transmission signal or all insulated metallic conductor cables under specific conditions is horizontal burning emitted smoke the transmission rate of the test.The standard IEC 61034 requires smoke box size is 3M³.
