Hi all,
I’m an engineering student working with acoustics, electronics and some FDM/SLA 3D printing. For my bachelor’s thesis I’m designing a small climate temperature chamber with monitoring and logging. It’s meant for simple soak tests, keeping prototypes/DUTs at a controlled temperature, and also things like SLA resin pre-heating.
I’d really appreciate feedback from electronics / embedded / test engineers, as well as related enthusiasts, hobbyists and makers, on what you’d actually want from such a chamber (temp control, logging, interfaces, safety, UI, etc.).
Short anonymous survey (~5 min) – no names or emails, results only used in aggregate for the thesis:

If there’s interest, I’d be happy to share an anonymized summary of the survey results here once it’s finished. If this post doesn’t fit, mods can remove it.
Thanks a lot to anyone who has a moment to respond

 

I have worked with such chambers, and the temperature control is certainly a big deal. The heat-only chambers are a lot less complex than the heat and cool chambers.
The big challenge is the product testing portion, because the need is to continually monitor the devices being tested to see if they go out of specification.

Using a testing chamber as an oven is quite inefficient, although it is certainly done. I suggest investigating the specifications of a commercial chamber, such as the "TENNEY" brand.
The design will not be that hard, all of the controls are readily available. And the electrical heating system likewise.
The system to check and monitor the parts being tested will be the difficult portion.

 

Thanks a lot for the detailed explanation, that really helps put things in perspective.
I’ll definitely look into the TENNEY chambers and focus more on how to properly monitor the parts under test rather than just the heating side. Appreciate you sharing your experience!
