Emission Test Chamber LETVOC
Application of Emission Test Chamber LETVOC
The LETVOC test chamber provides standard testing environment to determine the LETVOC emission rate and emission characteristics of interior decoration materials and products. Based on the test report,we can:
- Determine the impact of environmental variables on the LETVOC emission rate and emission characteristics.
- Classify the level of products and materials according to the emission characteristics
- Develop and adjust indoor air pollution models
- Evaluate the IAQ (Indoor Air Quality) according to the pollution data and test report
As being a significant means of LETVOC emission test,the LETVOC emission chamber finds a wide application in interior decoration,office furniture,engineered wood,carpets,plastics,.leather,textile,toys and more.
Advantages of Emission Test Chamber LETVOC
The coated stainless steel wall improves the adsorption capacity of test chamber for high-boiling-point materials and polar compounds.The recovery rate of tetradecane and 4-phenyl-1-cyclohexene can achieve more than 80%.
The patent is about how to deal with the connection surface between VOC emission chamber and the testing object.
The technology helps to reduce the surface adhesive force,largely reducing VOC’s adhesiveness on chamber’s interior wall.In this way,the testing result of samples stored in the sampling bag is more close to the result of testing object in chamber,and the testing precision of emission chamber is largely improved.

Testing Methods
- The air is first processed by compressor to remove solid particles,formaldehyde and volatile organic compounds,and then enters into the test chamber.
- The climate chamber is designed with an air jacket for conditioning the temperature in testing chamber.
- By adopting dew point method,the humidity of climate chamber is well regulated and controlled.
