test chamber

[Jacques]

hi to all. I have an idea. I would like to build a test chamber for testing electronic components and systems at different temperatures. My question is what is the best way to do this? What material should I use for the chamber? Any help appreciated.

Do you want a cooling test box for sub-zero temperatures or do you want a heating test box? Test box sizes?

I would like heating test box up to 100°C , size approx 30x30x30 cm or so...
