Working Principle 
Put sample of 1 square meter area into the temperature chamber which controlled control in a certain value of temperature, relative humidity, air velocity. The formaldehyde released from samples, mixed with the air in the cabinet, regular extraction in the air, and the air will be drawn through the absorption bottle is filled with distilled water, all the formaldehyde in air dissolve in the water; Measure the amount of formaldehyde in the absorption solution and extraction of air volume, and show it by micrograms per cubic meter (mg/m after), calculate the amount of formaldehyde in per cubic meter of air. Sampling is cyclical, until the test the formaldehyde concentration in the oven to reach equilibrium.

Overview:
Environmental parameters such as simulated temperature, humidity, air exchange times and sample surface air flow rate can be forced by the environmental chamber. Through the analysis and verification of the test data results, the release amount of volatile toxic and harmful (VOC) substances in the sample material and the impact of their release characteristics on the environment can be calculated, and then:
The effects of environmental variables on VOC emission and emission characteristics of test materials were determined
According to the VOC emission characteristics of the sample material, the grade of the material is divided
Research and development of sample materials and verification of indoor air VOC emission pollution characteristics
The VOC emission of the sample material decreases for a long time in the natural environment
The analysis based on the test data will predict the prediction and assessment of indoor air quality
