application
|
High or low temperatureThe low-pressure test chamber is mainly used in the fields of aviation, aerospace, information, electronics, etc., to determine the environmental adaptability and reliability testing of instruments, low temperature meters, electrical products, materials, components, equipment, etc. under the single or simultaneous action of low-pressure, high temperature, and low temperature, and can simultaneously measure the electrical performance parameters of the test piece when it is energized.

Box Structure
|
High or low temperatureThe low-pressure test chamber is processed and formed by CNC machine tools, with a beautiful and elegant appearance, and adopts a non reactive handle 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 enhances 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 observe the condition inside the box clearly at any time.
The bottom of the machine adopts high-quality fixable designPUActivity Wheel

|
control system
|
High or low temperatureThe temperature control instrument of the low-pressure test chamber adopts an imported touch screen and a programmable microcomputerPIDcontrolSSROutput operation, fully imported large LCD color touch screen display
The controller operation interface is available in both Chinese and English, and the real-time operation curve can be displayed on the screen;
havePIDThe function of automatic calculation can immediately correct temperature change conditions, making temperature control more accurate and stable.
Optional printer and computer connection.

refrigeration system
|
High or low temperatureThe refrigeration unit of the low-pressure test chamber is made of original French equipment“Taikang”Fully enclosed compressor.
America“Aigle”Dry filter, Taiwan“Guanya”Oil separator, Italy“Castel”solenoid valve
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, can make the temperature distribution in the testing area uniform.
The design of wind path circulation for air outlet and return 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.
