Product Details

VOC and Formaldehyde Release chamber

(VOC test chamber, VOC and formaldehyde emission test chamber, Volatile organic compound testing chamber)

Volatile organic compounds (VOC) testing chamber can help you ensure that your products comply with international VOC requirements that safeguard the environment and human health.

Because of their potential adverse impact on the environment and on human health, VOC are regulated in the manufacture of many products, especially those for indoor use where concentrations can be highest but also on paints and lacquers. The environmental effects of VOC include:

1. Direct effects and after photochemical conversion to secondary pollutants

2. Ground ozone formation
3. Damage to materials and buildings

4. Effects on human health from VOC tend to be chronic, rather than acute.

As a result more and more countries have opted for guidelines to reduce concentrations of VOC in consumer products. You need to be aware of the VOC requirements for your products and be sure that you comply.

Application of VOC emission chamber

1. The VOC test chamber provides standard testing environment to determine the VOC emission rate and emission characteristics of interior decoration materials and products. Based on the test report, we can:

l Determine the impact of environment variables on the VOC emission rate and emission characteristics.

l Classify the level of products and materials according to the emission characteristics.

l Develop and adjust indoor air pollution models.

l Evaluate the IAQ (Indoor air quality) according to the pollution data and test report.

2. As being a significant means of VOC emission test, the VOC emission chamber finds a wide application in interior decoration, office furniture, engineered wood, carpets, plastics, leather, textile, toys and more.

Testing methods

1. The air is first processed by compressor to remove solid particles, formaldehyde and volatile organic compounds, and then enters into the test chamber.

2. The climate chamber is designed with an air jacket for conditioning the temperature in testing chamber.

3. By adopting dew point method, the humidity of climate chamber is well regulated and controlled.

Advantages of VOC emission test chamber

The coated stainless steel wall improves the adsorption capacity of test chamber of high-boiling-point materials and polar compounds. The chamber absorbs more than 80% of tetradecane and 4-phenyl-1-cyclohexene.

Configurations

1. Interior structure

2. Sampling and testing holes (the hold number can be customized)

3. High-temperature catalyst container

4. Control system

The control system provides multiple languages.

Operation interface, testing data, curve graph, malfunction alarm, operation setting, program setting.
