Start from the test condition you have to produce. Each group links to the chamber that produces it and to the engineering note behind the choice.
Temperature and humidity
Steady-state heat, cold and humidity profiles, from benchtop units to standard cabinets.
Technical noteTemperature and Humidity Test Standards Compared: GB/T, GJB, IEC 60068, MIL-STD and JEDEC JESD22
Technical noteHow to Choose an Environmental Test Chamber: Volume, Temperature Range, Ramp Rate, Load and Humidity
Rapid temperature change and thermal shock
Where the ramp rate or the transfer between two zones is the specification.
Altitude, thermal vacuum and space
Low-pressure and vacuum chambers, including combined temperature and pressure duty.
Altitude (Low-pressure) Test Chamber — EQT Series
Rapid Decompression Test Chamber
Thermal Vacuum Chamber
Technical noteAltitude Chamber Low-Pressure Testing: Altitude–Pressure Conversion, Standards and Depressurisation Rate
Technical noteThermal Vacuum Chambers for Space: Vacuum–Temperature Coupling and the Cold-Black Background
Combined profiles, HALT/HASS and ESS
Temperature with vibration, and screening that has to run in production.
Temperature Humidity Vibration Test Chamber — EVT / EVTH Series
Four Combined Environmental Test Chamber — EQTH Series
HALT / HASS Test Chamber — ETH² Series
ESS Test Chamber — Environmental Stress Screening
Walk-in volumes and non-standard chambers
When the specimen, the floor space or the test item rules out a standard cabinet.
Walk-in Environmental Chamber — EWTH Series
Custom Non-standard Test Chamber
Mixed Gas Corrosion Test Chamber
Benchtop Environmental Chamber
Corrosion, dust, pressure and battery
For durability duty that is not temperature alone: salt spray, dust ingress, high pressure, accelerated humidity and battery abuse.
Composite Salt Spray Test Chamber
Sand and Dust Test Chamber — SDB / SDJ Series
High Pressure Test Chamber
HAST / PCT Test Chamber — EQ-PCT Series
Battery Test Chamber
Thermal Vacuum Cleaning System
Technical noteHAST and PCT Testing to IEC 60068-2-66: Conditions, Procedure and Chamber Choice
Technical noteConnector Thermal Shock to ANSI EIA-364-32C: Cycles, Evaluation and Chamber Setup
Icing, explosive atmosphere and specialised duty
Where the environment itself is the hazard: ice and freezing rain, flammable gas mixtures, and high-temperature baking.
