I have seen a few pictures of guys with what looks to be a blue Digital temperature gauge right in the collar of their Keezer?

I have been looking all over for one of these?
I've called probably three brew supply places and they don't have any or know where I can get one...

Does anybody know where I can find a blue or red Digital temperature gage to install in the collar of my Keezer?

Are you meaning one of these?

Is it a Johnson A419? They're supposed to be one of the best.

No that's not it... I think what you showed me is an actual controller..

When I say blue I mean the actual digital readout is a blue LED... And the unit is very small. guys actually cut a square in their collar of their Keezer and put it in...

I think this is getting pretty close....
The unit I saw, before the guy installed it, looked like it was quite a bit smaller and did not have a lot of buttons on the side.... And the actual LED readout was blue and not red

I've seen several keezer builds here using a love temp controller with a blue LED display. My guess is that's what you saw. Many of them used to come in your choice of red or blue readout, but it looks like most of them are only available in red now. Here's one that's still available in blue-

If you just want a display and not a controller, there are a few out there in blue. Lots more choices in red.

This is perfect! Thank you so much! I don't think I'm going to do the love controller, I think I'm going to choose one of the nine dollar LED temperature gauges... Which one do you think will be easier to install electrical-wise? One of them says it's ready to plug into a computer and the other one I think is just raw wires?

I have a friend who is going to help me but he is only a little bit savvy with electrical... I want to make his job easy...
Any ideas?

Badge, you are still going to need a controller. Is there a reason you want just the display and not just get a controller that has a nice display?

Well I haven't really thought about that... The guy at the homebrew shop said he had analog and digital and I think the digital he spoke of was the big blue unit that most guys have... Ugly ....
So my plan was just to buy that unit and put it on the back and buy that inexpensive $9.99 blue LED gauge and put it on the front of the collar...
It's just a probe and a power source so I figured it would be much easier then trying to install that controller love controller on the front of the collar.
It looked to me( on some videos I have seen on YouTube) that there was a lot of wiring involved with that process... I figured this way I simply bolt that other blue controller to the back of the Keezer and then just notch out the front of the collar for the blue LED temperature readout....
Whatcha think?

I'd just get a controller that you like the looks of and mount it in the collar where you want it. Wiring and routing the wires is easy, likely not much more difficult than wiring just the display. If you don't mind the red display, the e-bay aquarium controllers (STC-1000 and similar) are very cheap (~$20) and easy to wire. There's also plenty of how to's for those in the DIY forum here.
