Thermal Cycling Test Chamber

High and Low Temperature Test Chamber

Functional description:

Thermal cycling test chamber is a professional program-controlled environmental simulator that can simulate specific ambient temperatures from -40°C to +150°C. In the above temperature range, high temperature test, low temperature test, high and low temperature cycle test can be executed, and the test can be conducted under single conditions or combined conditions, and the editing of the test program is simple and easy to operate.

It can test the performance of the battery under high and low temperature, including charging and discharging performance as well as safety performance.

It can also test the performance of other materials or products under high and low temperatures, including stability, adaptability and aging performance, etc.

Applicable range:

Thermal cycling test chamber can be used for high and low temperature environment simulation test of batteries and other materials, such as thermal cycling test, thermal shock test, thermal stability test, thermal aging test, etc.

Applicable test standards:

1) GB/T2423.1-2008(IEC60068-2-1:2007) Environmental testing - Part 2: Test methods - Tests A: Cold

2) GB/T2423.2-2008(IEC60068-2-2:2007) Environmental testing for electric and electronic products Test methods - Tests B: Dry heat

3) Etc.


1)The adjustable temperature range of high and low temperature test chamber is wide, from -40 to +150, which can meet the requirements of various battery testing projects.

2)The inner chamber of thermal cycling test chamber is made of SUS304# stainless steel, which can withstand high and low temperatures, and has better corrosion resistance.

3)The testing holes and communication interface are reserved, which can be connected with the battery cell cycler. The test holes and communication interfaces are reserved to connect with the battery cell cycler, and the test software of the battery cycler can be linked to the thermal cycling test chamber, so the professional thermal chamber makes the battery test project easier.

4)The high and low temperature test chamber is equipped with various protection devices and complete protection functions, which effectively ensure the safe and reliable operation of the thermal cycling chambers.
