The SD-501 Series is a unique benchtop environmental test chamber.  The slim design takes up less space than any other chamber on the market today.   It fits perfectly in a standard 19” rack. Specifically designed to hold smaller test units, this test chamber is engineered to meet the most demanding testing requirements across a wide range of industries.

This benchtop test chamber is ideal for longer steady-state testing. Its unique slim style allows the chamber to be stacked one on top of the other in a server rack system allowing three independent tests to operate in the footprint of one test chamber.

AVAILABLE MODELS. The SD-501 series comes in three models, SD-501,SD-501-ATP optimized for battery testing, and SD-501-SAFE optimized to AES SAFE battery testing safety standards.  

STRUCTURE.  Featuring polished, heavy-gauge, stainless steel construction, inside and out, makes the SD-501 Series Test Chambers ideal for dust-free, sterilized environments. Between the internal and external layers, is highly-efficient, low K factor, thermal insulation This test chamber is built to withstand constant use and efficiency. 

Three specialized ports allow for cable patches to feed through the back of the test chamber workspace and easily connect to your battery cycler test equipment.

The slim design of this test chamber allows for highly controlled test samples or small batch testing with nine channels spread over three shelves.

CIRCULATION SYSTEM.  Air circulation is crucial for environmental testing. The SD-501 Test Chamber has a proprietary factory-adjustable baffle and fan design combination to optimize circulation conditions and temperature within the test workspace. 

HEATING SYSTEM. Featuring industry-leading heating systems, SD-501 Series Test Chambers are equipped with multiple low-watt density, ceramic core, nichrome heaters for accurate temperatures within ±0.5°C, as measured at the sensor. The arrangement of the heater gives you ultimate temperature precision. If your testing requires conditions drier than the surrounding ambient air, add an optional dry air purge or dry nitrogen purge system.

INSTRUMENTATION. SD-501 Test Chamber incorporates AESONE CONNECT®  creating a robust connected device giving you a standard and uniform interface that makes operation easier. Learn more in the Instrumentation Tab below.

*Rise and pull-down rates calculated using IEC 60068-3-5 standard. Custom options available.

*Ideal ambient temperature conditions for test chambers is 23°C (73.4°F). The temperature and humidity range of assured performance is between 15°C and 25°C (59°F/77°F) and 30-50% relative humidity. Conditions outside this range may affect the performance of your test chamber and reduce the lifespan of the equipment.
