Environmental Stress Screening chambers ETSP- ESS series
ETSP-ESS series are to conduct an Environmental Stress Screening test (Thermal cycling test) that is a process to precipitate process related defects from latent to patent for detection by a products verification test also to determine the limits of environmental stimulation which the product can endure before its performance is permanently degraded.
Solved noise, temperature variations, unbalanced air distribution inside the chamber.
- Slient compressors using ecologically friendly refrigerants.
- Unique air flow design to provide uniform temperature and humidity.
- Rapid temperature change rates.
- Friendly, flexible, up-to date control and management systems.
- Automatic water replenishment with low water alarm.
- Electronic humidity sensor.
- Allows easy servicing and upgrades.
- Oven networking connecting system (RS232/485)
