The high-altitude temperature test chamber is a comprehensive environmental testing equipment that combines low-pressure (high-altitude simulation) and temperature control, used to evaluate the performance stability of products in high-altitude low-temperature and low-pressure environments. The following is a detailed technical analysis and usage guide:
1 Core functions and technical parameters
1. Environmental simulation capability
Low pressure range:
Conventional model: 15 kPa (simulated altitude of approximately 12000 meters) to standard atmospheric pressure (101.3 kPa)
High end model: can be as low as 1 kPa (simulating an altitude of about 31000 meters, close to near space environment)
Temperature range:
Low temperature:- 70 C to+150 C (some aerospace grade equipment supports -80 C to+180 C)
Temperature fluctuation: 0.5 C (high-precision model)
Composite control: supports synchronous or cyclic testing of temperature, low air pressure, and humidity (optional)
2. Key performance indicators
Pressure rise and fall rate: 0.1~10 kPa/min (rapid testing or gradient simulation)
Temperature change rate: 1 C/min (linear) to 10 C/min (rapid temperature change model)
Humidity range (optional): 10%~98% RH (requires anti condensation design).
