The reference standards are: GB/T2423.1-2008 Test A Low Temperature Test Method, GB/T2423.2-2008 Test B High Temperature Test Method, GB/T2423.3-2006 Test Ca Constant Damp Heat Test Method, GB/T2423.4-2008 Test Db Alternating Damp Heat Test Method
The box is processed and formed by CNC machine tools, with a beautiful and elegant shape, and adopts non reactive handles for easy operation.
The inner lining of the box is made of imported high-quality stainless steel (SUS304) mirror panels, and the outer lining of the box is made of A3 steel plate spray painted, which increases the appearance texture and cleanliness.
The water replenishment tank is located at the bottom right of the control box and has automatic water shortage protection, making it more convenient for operators to replenish water sources.
The large observation window is equipped with lighting to keep the inside of the box bright, and uses tempered glass embedded in the heating body to observe the condition inside the box clearly at any time.
Separating the humidification system pipeline from the control circuit board can prevent malfunctions caused by water leakage in the humidification pipeline and improve safety.
The waterway system, pipeline, and circuit system are easy to maintain and repair.
The insulation of the box is made of ultra-fine glass fiber insulation cotton, which can avoid unnecessary energy loss.
There is a 50mm diameter test hole on the left side of the box, which can be used for external testing power or signal lines.

Product Features
1. Styling Design *:
Curved shape and surface spraying treatment, high-quality appearance, and flat non reactive handle, easy to operate, safe and reliable.
2. The large observation window has a wide and bright field of view:
Adopting a three-layer vacuum coating window and Philips energy-saving fluorescent lamp, there is no need for wipers to defog, maintaining clear observation effect, and the condition of the test sample can be observed at any time.
3. Separation of water and electricity ensures safety:
The separation of the humidification system pipeline from the power supply, controller, and circuit board can avoid the impact of pipeline leakage on the circuit and improve safety.
summary
It can accurately simulate complex natural environments such as low temperature, high temperature, high humidity, and low humidity, and is suitable for product reliability testing in various industries such as plastics, electronics, food, clothing, vehicles, metals, chemicals, and building materials.
