Brief Introduction of Structure
The internal test room is made by high quality SUS304 stainless steel; heat insulating material: high density
fiberglass wool; insulation material thickness: 80mm. The heat inside the internal room may not be conducted
to the outside, to keep balanced and stable temperature inside the internal room;
lOne transparent window is located at a proper position on test chamber door, to obverse the change of
specimen inside the internal room. The window is made by multi-layered tempered glass. The internal binding conductive coating is transparent, heat insulation, steam and
frost resistant and other advantages.
The mixing system adopts long axle fan motor, multi-blades wheel, made of stainless steel with good temperature resistance. The air is circulated forcedly vertically
in convection, to keep even and stable temperature inside the internal room;
The door and chamber body are sealed by high elastic double layer seal, with high temperature resistance.
The door inner plate is made by stainless steel. The door adopts non-reaction door handle, easy operation;
The test hole (at the left side of the machine) can be used for connecting power cable or signal cable (hole
diameter and number can be decided by the user).
The cooling system is installed at the bottom. The compressor is "Tecumseh", imported from France. The
single cooling system can guarantee that the temperature or humidity reaches the setting value within the
stipulated time.
The bottom of the test chamber is equipped with high quality PU moving wheels, which can be fixed. The
test chamber can be moved conveniently to the place required , finally fixed.
The control system is at the right side of the test chamber, including temperature controller and control
switches etc. convenient and easy operation and repair.
The air sampling system includes: sampling tube, two 100ml suction bottles, gas sampling pump, gas
flowmeter.
