The SD-501-3RS Series is a unique benchtop environmental test chamber.  The slim design, across the face, 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, it’s perfect for running temperature tests on lithium-ion batteries, small electronic devices, and growing organ cells for biotechnology companies.

Featuring polished, heavy-gauge, stainless steel construction, inside and out, makes the SD-501-3RS 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.

The slim stackable design of this test chamber allows for highly controlled test samples or small batch testing with nine channels spread over three shelves within each workspace, 27 concurrent tests.

Air circulation is crucial for environmental testing. The SD-501-3RS Test Chamber has a proprietary factory-adjustable baffle and fan design combination to optimize circulation conditions and temperature within the test workspace. 

Featuring industry-leading heating systems, SD-501-3RS 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.

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.

CONTROLLER   AESONE CONNECT allows for secure remote access to your test chamber and gives easy profile creation, operational control, and data management.

SD-501 Series Test Chambers have upgraded to include AESONE CONNECT creating a robust connected device for a standard and uniform interface making test chamber operation easier.

AESONE XCHANGE is hardware internal to the chamber that increases your functionality

  • Connects the test chamber controller to your network for increased accessibility
  • On-board multi-year data logging

AESONE SOFTWARE gives you the power to

  • Remote chamber operation and monitoring, 
  • Web-based test profile creation, 
  • Viewing current data and historical data visually
  • Secure multi-level user access
