Description: An equipment has multiple environmental chambers. It's a special formaldehyde VOC pretreatment environmental chamber for artificial board, which can proceed pretreatment for multiple samples at the same time (the number of environmental chambers can be customized according to the site and needs). This chamber is widely used in VOC pretreatment processes for building materials, toys and automotive interior product. It's particularly suit for the processing of man-made panels. 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.
Technical features: Multi cabin combination structure, capable of testing multiple samples simultaneously; Ultra low VOC background concentration control, multi-layer physical and chemical filtration purification; Advanced air sleeve temperature control technology, temperature and humidity adjustment technology, automatic recording of temperature, humidity, pressure, flow rate, etc
