The SCH-508-4-ATP, also known as the Super 508, is the most powerful temperature and humidity benchtop test chamber in the world and is specifically designed with rear wall ports to connect your battery cables to your cycler. The SCH-508-4-ATP can seamlessly integrate with our ATP® (All Test Platform) battery testing fixtures.

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 SCH test chambers in the same footprint.

STRUCTURE.  The internal workspace is lined with type 304 stainless steel for a vapor-tight internal construction. Two 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 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.

HEATING SYSTEM.  SCH test chambers feature heating systems equipped with stainless steel tubular fin heaters for reliable and accurate temperature control within ±0.5°C.

HUMIDITY SYSTEM.  The humidity system has a standard range between 10% and 95%. To extend your humidity range, see the optional features section. View RH Chart.  

COOLING SYSTEM.  The cooling system in the SCH-508-ATP consists of a self-contained mechanical refrigeration system with a single stage configuration and an air-cooling condenser. An optional water-cooled 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 refrigeration systems have the fastest standard change rates of any environmental test chamber manufacturer. See the Basic Specifications tab below. 

INSTRUMENTATION. SCH-508-4-ATP  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.
