Tianjin temperature and humidity control test chamber

Temperature and humidity control test chamber, also known as constant temperature and humidity test chamber, temperature and humidity test chamber, high and low temperature wet heat test chamber. This equipment is suitable for testing various performance indicators of aerospace products, information electronic instruments and meters, materials, electrical and electronic products, and various electronic components in high temperature, low temperature, or humid and hot environments.

Tianjin temperature and humidity control test chamberThe control part is designed on the right side of the equipment and is equipped with temperature controllers, control switches, etc. It is easy to operate, simple, and maintain.

Arc shaped design, smooth and natural lines, surface spray treatment, high-quality appearance, more clean and beautiful.

The outer shell of the box is processed and formed using high-quality A3 steel plate CNC machine tools, with a beautiful and elegant appearance. The surface of the shell is treated with spray coating.

The inner liner of the box is made of high-grade (SUS304) stainless steel plate, and the sample rack and other accessories inside the room are made of SUS304 stainless steel material.

The insulation material is high-density glass fiber cotton, with a thickness of 100mm/120mm.

The observation window is made of multi-layer hollow tempered glass, equipped with lighting fixtures, and the inner adhesive sheet conductive film is heated and defrosted to observe the test process clearly.

The temperature circulation system adopts a temperature resistant and low-noise air conditioning fan motor, and a high and low temperature resistant multi blade centrifugal fan wheel to achieve strong convection and vertical diffusion circulation.

A double-layer high temperature resistant sealing strip is used between the door and the box to ensure the sealing of the testing area, and a non reactive door handle is used for easier operation.

On the left side of the box, there is a test hole with a diameter of 25mm, 50mm, or 100mm, which can be used for external testing power or signal lines (any increase in the diameter or number of holes should be specified).

The waterway system and circuit system adopt side door opening, which is convenient for maintenance and inspection.

The bottom of the equipment adopts high-quality fixed PU movable wheels, which facilitate customers to move the equipment to the position and then fix the casters.

Tianjin temperature and humidity control test chamberPerformance technical parameters:

① Control method and features: Adopting the "balanced temperature and humidity control" control method, the SSR is controlled by PID method, combined with a specially designed air circulation system, so that the heating and humidification capacity of the system is equal to the heat and humidity consumption, thus ensuring stable use.

② The performance measured after two hours of stability under no test load and no scaffolding conditions. In addition, the rate of temperature rise and fall refers to the performance of air-cooled systems at room temperature+25 ℃ under no-load conditions.

The independent heating and cooling system enables the equipment to heat up and cool down more effectively, and the cooling system is a fully automatic control and safety protection coordination system.

Adopting a multi wing strong air circulation system to avoid any dead corners and ensure even temperature distribution within the testing area.

The air circulation design ensures that the air pressure and speed meet the testing standards, and can accelerate the temperature recovery time at the moment of opening the door.
