I have one extra control enclosure left over from my build.
Dimensions: 12.5" x 8.5" x 4" , has a 1.5" x 3.125" window in it. It has a panel inside to mount electronics on and a few electronic terminals, etc inside. There is a two digit digital screen of some kind still installed in the door. It appears to have read % of O2. Its NOT an LCD screen like that used in a Brewtroller. The door has a gasket and latch. Some switches and a buzzer are installed in the door. It will fit in the $14.50 Flat Rate Shipping box from USPS. I'm asking $35 plus shipping.
The panel in the background is not for sale. It's going to be my control panel housing the Brewtroller and other low voltage devices.
I'll measure it when I get home later but i have room for a dc power supply, BT, relay board. I have 5 SSRs so um putting them in a separate electrical junction box. I would say it's too small to put everything in one box. I'll send you a pic of what I have built so far.
