The VOC chamber is equipped with the voc cleaning module in the large replacement rate cabin, which can rapidly clean the cabin wall after the test and restore the environmental state of the test cabin within 3 hours. The new environment cabin is equipped with three special connection heads for sample tubes to facilitate voc sampling connection and avoid the impact of other connection materials on voc detection data.
The Wewon VOC emissions chamber is equipped with a recovery test sample injection port, which can be tested for recovery. The VOC test chamber is designed with a new type of circulating air duct. The air in the cabin is blown out from the top center and sucked into the gap between the four sides of the top, forming the formation of airflow tissue moving up and down.
