Application
FAQ
-
Q What is the maximum altitude (in meters) that this device can simulate?Our standard model can simulate low-pressure environments ranging from normal pressure to 0.5 kPa, corresponding to altitudes of approximately 30,000 to 45,000 meters. For special test requirements, an upgraded high-grade vacuum system can be adopted to further achieve deep-space environment simulations with pressures as low as 100 Pa or even lower.
-
Q How can I determine the appropriate size of the chamber based on my test samples?It is recommended that the sample volume should not exceed one third of the volume of the laboratory. This measure not only facilitates the loading and unloading of the samples, but also ensures the uniformity of air extraction inside the chamber. At the same time, in tests involving electricity and heat generation, it can reserve sufficient space for the installation of heat exchange and auxiliary cooling devices.
-
Q What impact does a low-pressure environment have on the heat dissipation of electronic products?In a low-pressure environment, the air becomes thinner, and the convective heat dissipation effect will significantly decrease. If the product being tested generates a large amount of heat during operation, please inform us in advance. We will re-calculate the cooling system configuration based on the actual heat load and assess whether additional liquid cooling or forced air cooling and other auxiliary heat dissipation solutions are needed.
-
Q What standards does this low-pressure test chamber comply with?This chamber is fully compliant with UN 38.3 (lithium battery transport testing), MIL-STD-810G (military standard environmental testing), and IEC 60068-2-13 (low pressure testing for electronic components). Custom compliance configurations are available upon request.
-
Q Can the chamber be used for testing lithium batteries safely?Yes. The chamber is specifically designed with battery safety in mind. It features explosion-proof pressure relief doors, automatic fire extinguishing devices, smoke sensing monitoring, leakage protection, and a three-color light alarm system. The door is also equipped with 2 explosion-proof chains to prevent it from being blown open during an incident.
-
Q Is the chamber size and configuration customizable?Yes. The chamber is available in two standard sizes (216L and 1m³), and both the inner liner thickness and terminal post size/quantity can be customized. Optional voltage-temperature conversion connectors with configurable channels are also available to meet specific testing requirements.
