Ozone Tester, Ozone Concentration: 10~500ppm, Size: 150 L

Main Purpose of Ozone Tester: Ozone tester popular used for rubber and plastic indsutry testing work. Ozone in the atmosphere is rarely the main factors of rubber cracking, ozone tester simulation and strengthening the atmosphere of ozone conditions, the study of the role of ozone on the rubber,
Rapid identification and evaluation of rubber anti-ozone aging performance and anti-ozone agent Protective effect of the method, and then take effective anti-aging measures to improve the service life of rubber products, the reference standard such as: GB : T7762-2003, GB : T2951.21-2008

Principles and Methods for Ozone Tester:

● Test method according to the test methods and standards can be divided into “static” and “dynamic”, static is the sample is stretched after the release of the test chamber to do the test, the dynamic is placed in the test box on the fixture, While doing the test, stretching the measured sample itself is about 5% -45%.

● The ozone tester used for: electrical, electronic products, components, parts and materials in high and low temperature environment, storage, transportation and use of the adaptive test. The ozone tester limited/ prohibits: flammable, explosive, volatile substances test or storage of samples; Test or storage of corrosive substances; Test or storage of biological samples; Test or storage of samples of strong electromagnetic emission sources
