|
application
|
High and low temperature alternating test chambers can generally be divided into programmable high and low temperature test chambers (touch screen)/Button type and single point high and low temperature test chamber. Used to test the degree to which material structures or composite materials can withstand continuous environments of extremely high and low temperatures, in order to test the chemical changes or physical damage caused by thermal expansion and contraction. The applicable objects include materials such as metal, plastic, rubber, electronics, etc., which can serve as a basis or reference for product improvement.

Box Structure
|
High or low temperaturealternationChamberThe 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 liner of the box is made of imported high-grade stainless steel（SUS304）Mirror panel, outer shell of the box adoptsA3Steel plate spraying increases the appearance texture and cleanliness;
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 clearly observe the condition inside the box at any time;
The bottom of the machine adopts high-quality fixable designPUActivity wheel;
Diameter on the left side of the body50mmThe test hole can be used for external testing power or signal lines;

|
control system
|
High or low temperaturealternationChamberImported digital touch buttons, PIDmicrocomputerSSRTemperature programmable controller.After inputting the data and experimental conditions, the controller has a locking function to prevent human touch from changing the temperature value;
The controller has a locking function to prevent human touch from changing the temperature value;
Optional printer.

refrigeration system
|
High or low temperaturealternationChamberThe refrigeration unit adopts the original French "Taikang" fully enclosed compressor;
The refrigeration system adopts a unit or binary low-temperature circuit system design;
Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, and ensuring even temperature distribution in the testing area;
The design of the road circulation air outlet and return air ensures that the wind pressure and speed meet the testing standards, and can quickly stabilize the temperature at the moment of opening the door;
Heating, cooling, and complete system independence can improve efficiency, reduce testing costs, increase lifespan, and decrease failure rates.
