Structure and characteristics
 The inner and outer shells are formed by high quality PP plastic plates through special molds, and the seam between the plates is formed at 90 degrees right Angle after planing and milling, and then the high temperature welding torch melts the plastic welding wire. After cooling, the weld is more firm, and the seam of the whole box is smooth and smooth, the box structure is compact, and the appearance is bright.
 Box cover material: the box cover is made of high-quality PP impact resistant plate, with double-sided transparent observation window, which is easy to observe the test status of the test samples during the test. The box cover and the box body are sealed with water to prevent gas overflow. The box lid adopts 110 ~120 corners to ensure that the condensate does not drop on the specimen, and the box is equipped with pressure balance hole and condensate discharge hole.
The temperature in the test box is heated by the bottom water, and the box temperature is more uniform and stable. The heating element adopts titanium heating pipe for salt and corrosion resistance and long service life.
The sample frame structure design is reasonable, "V" groove + bar, convenient Angle adjustment, large weight, easy to place the test product.
Attached with double overtemperature protection, insufficient water level warning, to ensure the safety of use.

Installation should know and matters needing attention

1,Power supply: AC220V / 50Hz power is about 3kw
2,At least 80cm away from the left and right walls of the machine, it is easy to operate and repair, and no other equipment and items should be placed in the room to avoid corrosion;
3,Avoid direct sunlight;
4,Do not knock and force collision, resulting in rupture, the use of temperature do not exceed the test standard range, so as not to deformation due to overheating;
5, The drainage pipe and exhaust pipe can be connected with hard pipe or plastic hose, pay attention to the water pipe mouth should be down, and diluted with tap water; the exhaust pipe extends to the outdoor discharge;
6,Keep the box clean and clean with water;

ambient condition

1,temperature:18ºC~+28ºC
2,Relative humidity: 70% RH
3,No strong vibration around;
4,No direct radiation from other heat sources;
5,There is no strong air flow around, when the surrounding air needs to be forced to flow, the air flow should not be directly blown to the box;
6, The test box should be placed smoothly and kept level;
7,There should be a certain distance around the test box for easy operation and maintenance.
