Formaldehyde Testing Chamber / Climate Test Chamber High Accuracy
It is used to test formaldehyde emission of various wood-based panel, composite wood flooring, carpet, carpet padding, and other interior decoration materials, also other building materials under constant temperature humidity.
EN 717-1 Wood-Based Panels Determination of Formaldehyde Release-Part 1:FormaldehydeEmission by the Chamber Method
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.
