Construction

(1.)Test chamber in all three walls:

inner wall-mirror stainless steel

middle-rock wood insulation wall

outer wall-spray material

1. )Non-releasing,non-adsorbing materials in the chamber

(3.)There has air-inlet,testing,sampling at chamber. Air-inlet connect with regulation valve of common clean air source.

Common clean air source

Common air source is composed of turbo fan motor,particle filter, VOC filter, formaldehyde filter,humidity generator,constant temp control unit, air flow control unit and so on.

Air flow：total≥2 m³/h。

Cleanliness:

 concentration of formaldehyde≤0.005mg/m³

Single concentration of VOC≤0.002mg/ m³

Concentration of TVOC≤0.02mg/ m³

Dew-point temp：5℃--40℃

The air distributor divided into multiple channels, be controlled respectively.
