Environmental Test Chambers

Low pressure test chamber JOEO  Electrical,electronic,military industry and household products.According to GB,GJB and IEC standard,to do high low temperature,humidity thermal,low pressure and other environmental and reliability test.

JOEO altitude chambers,altitude test chamber is composed of test room formed by pressure-containing box shell and insulation structure, refrigeration system, add wet system,vacuum system and electric control system and other components.Low pressure test chamber JOEO is precision instruments support great extent electronics parts quality test than standard test chambers,for example - Military products.
Low pressure chamber are meet international standards DO160, ASTM, MIL-STD-781, -810 Altitude up-to 150,000 feet
Temperature range -70°C to +180°C, Humidity range 20 to 95%.

JOEO ESS chambers are 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.Temperature range from -70℃ to +180℃ and relative humidity from 5% to 98%. Rate of temperature change (3℃/min,5℃/min,10℃/min,15℃/min).
This type of temperature humidity chamber 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.

Altitude Test Chamber of JOEO factory is designed to allow users to perform temperature, humidity, and altitude condition tests in a combined test chamber, and create multiple conditions to meet multiple test requirements at the same time. 
Altitude chambers designed to simulate altitude conditions up to 100,000 feet. 
Provides simultaneous temperature/altitude testing from site altitude to 65,000 feet for high altitude test chamber testing. 
Humidity test can only be performed at the altitude of the site. 
Heated inspection window to ensure that the test room is clearly visible.

From aerospace and avionics to refrigerators and automobiles, JOEO panelized large environmental chamber serve as testing grounds for components and finished products. Knowing the size, quantity, and test requirements of your product can help you determine the best chamber size for your application. If our standard equipment does not meet your test requirements, we will design a custom test box that can meet your test requirements.

CATL  Battery Walk In Test Chamber

JOEO Walk In Test Chamber's temperature cyclic stress screening is to change the external environmental stress by using the temperature acceleration technique (the product produces alternating expansion and contraction when circulating in the upper and lower extreme temperatures) under the design strength limitation, so as to generate thermal stress and strain in the product.

It can set different stress screening temperature change rate 5℃/min,10℃/min,15℃/min,20℃/min 
Walk In test chamber(ESS chamber) is suitable for the whole product, parts and materials for high temperature, low temperature, high and low temperature cycling & temperature stress screening (ESS) test and constant humidity and cyclic damp heat test.
