SD & BHD Series

The SD and BHD Series are our standard benchtop environmental test chambers.

SD chambers are temperature only, whereas BHD chambers include a humidity capability with levels anywhere between 10% and 98% (± 2%) relative humidity.

Available in four different volumes, we have the benchtop environmental test chamber to fit your testing needs.

SD and BHD environmental test chambers are capable of producing a wide temperature range from -65°C to +180°C (-85°F to +356°F).

AES' custom-designed inner-baffle design increases temperature stability and maintains even air circulation. This airflow consistency allows for highly-accurate environmental testing on your product. These benchtop test chambers are ideal for small-scale thermal cycling tests and can be outfitted with a liquid-cooled boost to improve the functionality of the test chamber.

SD/BHD Configurations:

  • SD/SDE-01 - Temperature only
  • SD Series - 300 and 500 Models Temperature only
  • BHD Series - 200 and 500 Models Temperature and humidity

Available in four standard temperature ranges:

  • Series SD/BHD-300  -65°C to +180°C (-85°F to +356°F)
  • Series SD/BHD-500  -37°C to +180°C (-35°F to +356°F)
  • Model SD-01              -20°C to +80°C (-4°F to +176°F)
  • Model SDE-01            -35°C to +120°C (-31°F to +248°F)

Safety Measures

We offer multiple types of safeties on our test chambers to help protect your product and your test chamber if anything malfunctions.

Heat Fuse: (Standard)

A heat fuse or thermal fuse, will interrupt the flow of electricity to the test chamber and shut it down if it reaches a certain temperature.

High Temperature Safety: (Standard)

A digital set temperature safety that will shut down the test chamber if it goes over a certain temperature.

High/Low Temperature Safety:

A digital set temperature safety that will shut down the test chamber if it goes over a certain temperature or below a certain temperature.
