The ITM-LAB GDJZ Series combines high- and low-temperature testing with reduced air pressure simulation to evaluate product reliability under controlled environmental conditions.
Designed for aerospace, electronics, telecommunications and industrial applications, the series offers low-pressure simulation down to 1 kPa, customizable chamber capacities and application-specific temperature configurations.
Equipment operating at high altitudes may experience reduced atmospheric pressure alongside changing temperatures. These conditions can affect thermal management, electrical insulation, sealed components and overall equipment reliability.
The GDJZ Series enables temperature and low-pressure exposure within a single chamber, supporting environmental reliability testing, product development and qualification programs.
Test conditions are configured according to the required temperature-pressure profile, specimen characteristics and applicable test procedure.
The GDJZ Series combines temperature regulation with controlled pressure reduction for altitude simulation. Based on the published series specifications, temperature fluctuation is ±0.5°C, temperature deviation ≤±2°C, and temperature uniformity ≤2.0°C under specified test conditions.
The pressure system supports simulation down to 1 kPa, with adjustable pressure transition rates. Temperature and pressure performance under simultaneous operation depend on the selected configuration and test conditions.
Chamber capacity and internal dimensions can be customized to accommodate different specimen sizes, test loads and laboratory requirements.
The chamber features a SUS304 stainless steel interior, insulated construction and an observation window for monitoring specimens during testing. Chamber dimensions, specimen supports and selected accessories are determined by the application.
The GDJZ Series can be configured with supporting cooling equipment according to chamber capacity and thermal requirements.
The actual ITM-LAB project shown here incorporates an external industrial chiller connected to the environmental chamber, demonstrating an application-specific system configuration.
The GDJZ Series supports application-specific configurations. Published performance values should be interpreted according to the selected model and stated test conditions.

The appropriate test profile depends on the product's operating environment, exposure duration and applicable standard.
The GDJZ Series can be evaluated for environmental test procedures involving temperature and reduced air pressure, including:
IEC 60068-2-13 — Low air pressure
IEC 60068-2-1 / IEC 60068-2-2 — Cold and dry heat
IEC 60068-2-40 — Combined cold/low air pressure
RTCA DO-160 Section 4 — Temperature and altitude
MIL-STD-810 Method 500 — Low pressure (altitude)
Suitability for a particular standard or test category must be confirmed against the required temperature-pressure conditions, exposure duration, specimen load and equipment configuration.
Listing these standards does not imply certification or compliance with every procedure.
