Guangdong Zhongzhi Testing Instruments VOC Pretreatment Chamber/Clean Chamber is mainly used for environmental simulation tests such as environmental stress screening of automobile materials, products and other materials, including: temperature, air conversion rate, air flow rate, clean air background concentration or simulated real indoor environment, and test the pollutant release rate and release characteristics of various interior parts and products, determine the impact of environmental variables on the release rate and release characteristics of materials and products: thus classifying materials and products according to release characteristics; developing and verifying models for predicting indoor air pollution; evaluating indoor air quality (IAQ) based on indoor pollutant data or prediction models, etc., and then determining whether it will produce harmful substances or cause performance degradation when it is subjected to changes in the surrounding environment. Provide a basis for product design, production, improvement, identification, factory inspection, etc.
