Default Johnson temp controller

I am looking to get a controller for my extra fridge for brewing and was wondering if anyone has used these and how they like them. AHS has the digital ones for 79, I thought that would work pretty good.

There are a lot of threads with more specifics, but Johnsons are exceeding common around here and are generally well liked.

I just purchased a Ranco temperature controller the other day. I purchased it at Grainger industrial supply here in Rochester. I get a discount there so I decided on them.

It works very well for me. I'm using it on a freezer I have in my basement.

I have two analog johnsons and aside from the numbers on the dial being pretty much meaningless they work very well. I just have to use a thermometer and get it set where I want it.

Will it work with a regular refrigerator? I see that the advertising says turn any freezer into.....I assume a fridge would work just the same?

Sure. Obviously, the fridge is going to have a different operating range than the freezer, but so long as you are looking to maintain an operating temp appropriate to your fridge you're good. A lot of people prefer using fridges to freezers at above freezing temperatures due to moisture concerns.

You know, I have been meaning to post about this for 6 months or so, and haven't. I built a fermentation chamber and have an analog johnson controller (can't recall the model). The numbers are way off, like by 5-10 degrees. Meaningless, like you said.

Is this the norm with these controllers? I just use a thermometer to check the beers temp to help dial in the right setting...so it works, but man are those numbers useless. I thought I just had a bum unit.

Other than that, the unit works great and keeps a steady temp.

75 Plus shipping.....AHS 79 and buy a kit and they ship it to my door for free ( orders over 100 ship free) .

I heard the digitals are more accurate than the analog, but if I have to use a therrmometer to dial in the temp no big deal.

It is priced at $65 / Total Price $72.60 with shipping (Las Vegas, NV).

I received mine the other day. It is a very nice controller.
