Q: Can the GDJZ-535L-B meet strict military and aerospace environmental testing standards?
A: Yes. With a temperature range of -40°C to +150°C and low-pressure simulation down to 1kPa, this chamber is perfectly engineered for rigorous reliability testing of aerospace components, avionics, and telecommunications hardware.
Q: How long does it take for the chamber to pull down from standard atmospheric pressure to 1kPa?
A: It drops from standard atmosphere to 1kPa in ≤ 20 minutes (empty load). It also supports an adjustable altitude simulation rate from 500ft to 5,000ft/min to mimic rapid ascent profiles.
Q: How does the chamber prevent pressure and temperature data drift during long-term testing?
A: The heavy-duty SUS304 stainless steel interior ensures a perfect vacuum seal. This maintains a tight temperature fluctuation of ±0.5°C and restricts pressure deviation to ≤ ±0.1kPa at ultra-low pressures (≤2kPa).
Q: What is the maximum physical payload the internal chamber can support?
A: The reinforced 535L interior supports a maximum structural payload of up to 50kg, making it suitable for bulky electronic enclosures or heavy battery modules.
