Faster Temperature Humidity Chamber (JOEO ESS chambers) high low temperature chambers, environmental testing equipment is suitable for the whole product, parts and materials for high temperature, low temperature, high and low temperature circulating and temperature stress screening (ESS) test, and constant humidity and cyclic damp heat test. This type of JOEO temperature humidity controlled chamber (ESS chambers）mainly used to simulate the product in climate conditions, a temperature and humidity conditions or at ambient temperature and humidity conditions, detecting the product features and the adapt change ability. It’s the aviation, automobiles, home appliances, research and other fields necessary test equipment.
Meet Standards
IEC 62133-2017 UL 1642 UN 38.3
Product Features
environmental stress screening chamber (JOEO ESS chambers) refers to the process of exposing a newly manufactured or repaired product or component (typically electronic) to stresses such as thermal cycling and vibration in order to force latent defects to manifest themselves by permanent or catastrophic failure during the screening process. The surviving population, upon completion of screening, can be assumed to have higher reliability than a similar unscreened population.
Temperature control chamber (JOEO ESS chamber) Can set the temperature variable rate of the different stress screening
Rapid Temperature Change Test Chamber Can perform a rapid temperature change (ESS), condensation test, high temperature and humidity test, temperature and humidity cycling test, etc.
Meet requirements of stress screening test（ESS Test） for electronic equipment
Test methods:Switching temperature & average temperature
JOEO ESS chambers Support variety of stress screening (fast temperature change rate) 5deg C/min, 10deg C/min, 15deg C/min experimental conditions
Rapid Temperature Change Test Chamber have 2 test methods:
①temperature test ②average temperature test
With aluminum sheet test machine load capacity (non plastic load)
Single machine can perform fast temperature change (ESS), condensation test, high temperature and humidity test, temperature and humidity cycling test, etc.
Following sample load customized with a large ESS Chamber
Built in two-way USB2.0 portable storage interface (can copy the test curve and load the test program)
Complete real-time test curve analysis shows that no time limit
Can be integrated with the E management system to monitor the management system
Multi-language selection: Chinese, English, Russian, Korean, Japanese, German multilingual language switching.
