Application:

The low-pressure test chamber is mainly used in aviation, aerospace, electronics, defense, scientific research and other industrial sectors to determine the electrical and electronic products (including components, materials and instruments), etc., under the action of high and low temperature and low pressure, respectively, for reliable storage and transportation. Sex test, and the test piece can be energized at the same time to test the electrical performance parameters.

Features:

1. The low-pressure test chamber is machined and formed by CNC machine tool. It has beautiful appearance and adopts no reaction handle, which is easy to operate.

2. The inner bladder of the box adopts imported high-grade stainless steel (SUS304) mirror panel, and the outer shell of the box is sprayed with A3 steel plate, which increases the appearance texture and cleanliness.

3. Temperature control instrument adopts imported touch screen, programmable microcomputer PID control SSR output operation, all imported large LCD color touch screen screen, controller operation interface is available in Chinese and English, real-time running curve can be displayed by screen;

120 sets of programs, each group of 99 segments, each segment can cycle 999 steps of capacity, each period set the maximum value of 99 hours and 59 minutes;

4. The chiller adopts the French original "Taikang" fully enclosed compressor.

5. Multi-wing blower is used to strongly supply air circulation, avoiding any dead angle and making the temperature distribution in the test area uniform. The wind path is designed to return to the wind and return to the wind. The wind pressure and wind speed are in compliance with the test standards, and the temperature can be stabilized at the instant of opening the door.
