Formaldehyde VOC test chamber environmental chamber uses and principles.

The VOC test chamber environmental chamber produced by Dongguan Huan Yi Instrument Technology Co., Ltd. can provide a standard test environment (such as specified temperature, relative humidity, air replacement rate and airflow rate) or simulate a real indoor environment and test the pollutant release rate and release characteristics of various indoor materials and products, which in turn can

Determine the effects of environmental variables on the release rates and release characteristics of materials and products.

Classify materials and products based on their release characteristics.

Develop and validate models for predicting indoor air pollution.

Evaluation of indoor air quality (IAQ) based on indoor pollutant data or predictive models.

Testing principles of the VOC standard test chamber environmental chamber.

The process of testing pollutant releases from environmental chambers can be outlined as follows: materials and products or their samples are placed in the test chamber; environmental conditions such as temperature, relative humidity and air replacement rate in the chamber are adjusted as needed; samples are taken at the exhaust port or inside the environmental chamber; gas samples are analyzed using appropriate methods to identify the major pollutants and their concentration changes over time; and then the release of materials and products is determined from the measured concentrations The measured concentrations are then used to determine the release rates and release characteristics of materials and products.
