TestEQ (Dongguan Desi Environmental Instrument Co., Ltd.) designs and manufactures environmental test chambers and reliability test systems. The range covers temperature and humidity testing, temperature change testing, combined-stress testing, accelerated life testing, large walk-in and custom systems, and vacuum / low-pressure chambers. Chambers are configured around the customer’s test standard, specimen size and thermal load.
Temperature and climate chambers
- High and Low Temperature (Humidity) Test Chamber — ETH series, -40 °C / -70 °C to +180 °C, 245–1000 L, 10–98 % RH.
- Standard Climatic Test Chamber — general temperature and humidity simulation for reliability and qualification testing.
- Benchtop Environmental Chamber — compact 22.5 L and 64 L chambers for component-level testing.
Temperature change chambers
- Thermal Shock Test Chamber — ETS series, two-zone and three-zone rapid temperature shock.
- Rapid Temperature Change Chamber — EATH series, 5–30 °C/min controlled ramp rate.
Combined-stress chambers
- Temperature Humidity Vibration Test Chamber — EVTH series, AGREE three-in-one testing.
- Four Combined Environmental Test Chamber — EQTH series, temperature, humidity, vibration and altitude in one profile.
Accelerated life and screening chambers
- HALT / HASS Test Chamber — ETH² series, combined thermal and multi-axis vibration stress.
- ESS Test Chamber — environmental stress screening for production defect screening.
Large-scale and custom chambers
- Walk-in Environmental Chamber — EWTH series, 7.8–44.1 m³ and larger welded rooms.
- Custom Non-standard Test Chamber — engineered-to-order chambers for special test conditions.
- Mixed Gas Corrosion Test Chamber — IEC 60068-2-60 flowing mixed gas corrosion testing.
Vacuum and low-pressure chambers
- Altitude (Low-pressure) Test Chamber — EQT series, temperature, humidity and altitude simulation.
- Rapid Decompression and Explosive Decompression Test Chamber — 10,000 m pressure differential in 15 s, explosive decompression in 0.1 s.
- Thermal Vacuum Chamber — space simulation for aerospace and satellite testing.
Specialised and safety test chambers
- Icing Test Chamber — controlled ice accretion and freezing rain simulation.
- Explosive Atmosphere Test Chamber — fuel vapour and explosion hazard testing.
- Semiconductor High Temperature Oven — EUT series, RT to 200 °C, wafer baking and curing.
Chambers can be configured for test programs based on GB, GJB, IEC, ASTM, UL, MIL-STD and JEDEC JESD22 requirements. For a specific temperature range, chamber volume or test profile, contact us with the specimen dimensions, test standard and required conditions.
