The SD-501-SAFE 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-SAFE 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 design of this test chamber allows for highly controlled test samples or small batch testing with nine channels spread over three shelves.

Air circulation is crucial for environmental testing. The SD-501-SAFE 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 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.

Safety Features


  • High/Low Temperature Control. An adjustable temperature limit controller allows you to program the highest lowest temperature the device under test, protecting products from compromising temperature exposure.
  • Internal high-temperature limit safety
  • Refrigeration system over-pressure safety circuit
  • Emergency Shutdown Switch
  • TUV Rheinland certified meeting UL-508A

  • Chamber Alarm Input. Sends a voltage signal that when interrupted will trigger an alarm state and shut down the chamber
  • Chamber Alarm Output. When the chamber is powered and in a safe state the contact closes. Loss of power or alarm condition opens the contacts
  • Rapid Temperature Change. Chamber air temperature sensor or product sensor monitored for a temp change greater than the capacity of the chamber over time
  • Audible and Visual Alarm. Emits audible alarm when chamber is in alarm condition
