BenchtopRack and Stack

TUVRheinland icon Benchtop Stackable icon

The SD-508 is a benchtop-style environmental test chamber for temperature-only testing.  Designed for precision and accuracy, this test chamber is engineered to meet the most demanding testing requirements across a wide range of industries.

If you are concerned about losing your lab counter space, this test chamber has an optional floor stand for one chamber, or get double the test workspace when you stack two SD test chambers in the same footprint.

AVAILABLE MODELS. The SD-508 comes in three models, SD-508,SD-508-ATP optimized for battery testing, and SD-508-SAFE optimized to AES SAFE battery testing safety standards.  

STRUCTURE.  The internal workspace is lined with type 304 stainless steel for a vapor-tight internal construction. The exterior has a durable powder-coat finish over heavy-gauge steel for a long-lasting clean look. Between the two layers is highly efficient, low k-factor, thermal insulation. This chamber is built to last for many years.

CIRCULATION SYSTEM.  Air circulation is crucial for environmental testing. The SD-508  Test Chamber has a proprietary baffle and fan design combination. This optimizes temperature conditions within the workspace. 

HEATING SYSTEM.  SD test chambers feature heating systems equipped with open ceramic-core nichrome heaters for reliable and accurate temperature control within ±0.5°C.

COOLING SYSTEM.  The cooling system in the SD-508 consists of a self-contained mechanical refrigeration system with a single stage configuration and an air-cooling condenser. An optional water cooling condenser is available.  

Add boost cooling with liquid LN2 or CO2 for even faster pull-down rates. It's a great option for stress tests that require rapid cooling.  

Even without boost cooling, AES’ standard cascade refrigeration systems have the fastest standard change rates of any environmental test chamber manufacturer. See Basic Specifications tab below. 

INSTRUMENTATION. SD-508  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.
