Default ISO cheapest digital temp display...

that can accommodate a K type temp probe?

It doesn't need to do anything other then show the reading....so no SSR control needed.

Suggestions?

I'm trying to find the one I had looked at one ebay at one point. I think it was something like $17 shipped. I do remember that it was pretty darn large in size, though...

I can't find the one I had stumbled across a few months ago.

The least expensive ones I am seeing (under $10) come with their own probes (not specificed exactly what kind they are either.)

I found some that take input from a K-type thermocouple, but they only display Celsius. Listed for appx $30, but it's one of those "or make an offer" items:

EDIT: You could get another cheap, single display PID and just use it to monitor the temps... possibly put it to better use later if you found a reason. You can get them on ebay for about $30 or so. I can't seem to find any thermometer ONLY items that will allow you to use a K-thermocouple for less than buying another cheap PID.

Yeah that's what I figured.

Planning on tossing 4 of them in my planned Temp Cabinet (1 for each brew) and was hoping to find something Love small but dirt cheap...

Ah well...can't have everything.

are you dead set on using k-type thermocouples for some specific reason?

If you use the 1-wire sensors you could hook 4 to a brew-troller (fermtroller), and it would be cheap. All 4 temps in 1 LCD display too!

Wish I could remember where I got mine now. Maybe Harbor Freight? AA battery, digital, 2-probe (hardwired probes) for indoor/outdoor temps with switch on face to switch between the two. Works great and accurate to 0.2 degrees F. Had it for probably 15 years now.

....... like this?

This is super cheap and could be used, however you might have to modify the probe a bit depending on you intend to mount it in a fermenter.

Yeah, there are a lot of inexpensive digital thermometers out there, some costing as little as $3 shipped.

But the OP wants one that he can connect a K-thermocouple to.

I was set on K-type, as I have 7 of them on hand...but it may be more beneficial to go lesser probe and cheaper display.

Does the BCS connect with K's? I may go that route instead...be nice to hit my ferm cabinet from the internet
