Product Information:
The equipment is mainly used for the determination of free formaldehyde emission from consumer products such as wood products, furniture, flooring, carpets, footwear, and building decoration materials.Test specimens with a known surface area are placed into the test chamber, where temperature, humidity, air velocity, and air exchange rate are controlled at specified levels. Formaldehyde is released from the specimens and mixed with the air inside the chamber. Air samples are periodically extracted from the chamber and passed through a gas washing bottle containing water, where the released formaldehyde is absorbed and its concentration in the water is measured.The formaldehyde concentration in the test chamber air is calculated based on the formaldehyde concentration absorbed in the gas washing bottle and the volume of extracted air, and is expressed in milligrams per cubic meter (mg/m³). Sampling is performed periodically until the formaldehyde concentration inside the test chamber reaches a stable equilibrium state.
