GA-9024 플라스틱 연기 밀도 테스터

Instrument use:

Plastic combustion smoke density tester is based on the national standard GB/8323.2-2008 provided by the technical conditions and research and development of a new type of measurement of smoke density test equipment, this standard is suitable for the determination of plastic combustion smoke generated by the density of light, and the maximum density of light as the test results.It is used to evaluate the smoke properties of plastics under specified conditions.

In line with the GB8323.2-2008 “플라스틱 – smoke generation – part 2: single chamber method to determine the smoke density test method” and ISO5659.2-2006 “플라스틱 – smoke generation – part 2: single chamber method to determine the optical density” test standards.The whole instrument is composed of closed test chamber, photometer measuring system, radiation cone, combustion system, igniter, test box, bracket, thermometer table and smoke density testing software;The circuit is developed by single chip microcomputer with high technical content and stable performance.This instrument is suitable for all plastics, also can be suitable for the evaluation of other materials (such as rubber, textile coverings, 코팅, wood and other materials), is widely used in the plastics industry, solid materials industry production plants and scientific research and testing units.
