Construction
|
(1.)Test chamber in all three walls:
inner wall-mirror stainless steel
middle-rock wood insulation wall
outer wall-spray material
- )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.
