    Enviromental Test Chamber
    Constant temperature & humidity test Chamber                         Cold and heat shock test Chamber
    Constant temperature humidity test Chamber & Cold and heat shock tester the difference

    The programmable constant temperature and humidity test box can also be called a programmable wet heat alternating test box, or a programmable constant temperature and humidity testing machine. From the name point of view, it can be known that his range of application is related to temperature and humidity. He can do temperature and humidity changes or constant tests on the sample. The heating rate is about 4°C/min and the cooling rate is 1°C/min. and

    Hot and cold shock test box, from the name of the word "impact" can guess his fierce degree. It is true that his temperature conversion time is much faster than that of a constant temperature and humidity chamber. Hot and cold shock chambers can be converted within 5 minutes - if you want faster we can customize the instrument within 3 minutes - to achieve the temperature conversion, for example you want to increase the test temperature from -60 °C to 120 °C, Or from 120 °C to -60 °C, the conversion can be completed in 5 minutes or even 3 minutes. This demanding requirements are mostly used in auto parts, photovoltaic components and other industries. Therefore, from the technical point of view, the content and technical difficulty of the hot and cold shock test box will be much higher than that of the constant temperature and humidity test box. However, it is not necessarily said that the use of a thermal shock chamber covers a constant temperature and humidity chamber. For example, the thermal shock test box has no function of humidity control.

    Therefore, when purchasing, depending on the customer's test standard, choose the equipment that suits you.

    Working Principle

     This is so called Fast Shipping Thermal Shock Test Chamber,Thermal Chamber,Thermal Shock Chamber.
    Sample is placed in the test chamber, more extreme temperature than test temperature can be set in high-temperature chamber and low-temperature chamber. When it comes to low temperature test, cold chamber door open, and low-temperature chamber working together with test chamber.

    When converted into high-temperature test, cold chamber door closed, hot chamber door are opened, and test chamber working together with high-temperature chamber.

    Conversion of mechanical action (transferring from high temperature to low temperature or low temperature to high temperature) can be completed in less than 1second, and the temperature can be quickly stabilized. During the whole test, test sample is no need to be moved, and without any human intervention.


    Fast Shipping Thermal Shock Test Chamber,Thermal Chamber,Thermal Shock Chamber have been designed to operate in accordance with reliability programs, quality control, commercial test programs and medical tests. It is used to test the capability of material structure or composite material to withstand the continuous environmental changes between extremely high temperature and low temperature during a short period. It is applicable to metals, plastic, rubber, electronics amongst other materials. The test result can be used as a reference or basis for produce improvement.


    1.Thermal shork chamber in each zone for peak demand of heating and cooling. Provides extra thermal energy to efficiently meet the MIL-STD 883 requirements.
    2.Temperature recorder provides 24 hour part temperature recording as the load travels from zone to zone. Using touch-control graph control as operation interface, easy to operate.
    3.The system can be used for automatic Circulation Shock or manual selective shock, capable of setting two zones or three zones shocks as well as cold and thermal shock start-up.
    4.Custom-made and optional accessories available.
