So my last two brew days were stressful as hell. First my dial thermoms wouldn't stay in calibration. Then I bought a nice floating thermom which broke halfway through the brew day. I am tired of the crappy thermoms. Could some one recommend a good digital thermometer?

Thanks
 
I'm somewhat of an veteran on this, having been burned by two $40 digital waterproof (but not heatproof past 122f, I found out) thermos. After being told that I wast stupid for not "knowing" that the sheathing on those thermometers was only rated to 122f, even though none of the literature said so, and subsequently writing a scathing letter to the company, they gave me a refund for both failed thermometers. When I spoke to the company that made the failed ones, they said that those were not good for beer brewing, and recommended a "Type K" thermocouple.

So with my refund $$ from the previous failed ones, I purchased this indicator:

...and a type-K probe (scroll down to "PTFE/FEP Tip Probes", I bought model #113-372-T):

I drilled a small hole in my mash cooler lid to feed the probe into the mash, and have been very happy with it. You can find the indicator and probe for less $$ on eBay, but after all those failed thermometers, I wanted the peace of mind of a supplier-backed warranty.
 
This is good advice. I am wondering if I could just get one of the Type K temp probes like Evan mentioned (...and a type-K probe (scroll down to "PTFE/FEP Tip Probes", I bought model #113-372-T)

and plug it into my multi meter with has a temperature option that takes a Type K as the input.

Has anyone tried this? I wouldn't mind skipping the $40 for the handheld portion if I can.

If it says it takes type k probes, then I see no reason why it wouldn't work...

Yep it does, it came with a probe too but I doubt that it is water proof or heat proof as you found with your previous models.

Right now it is just a neat toy to turn on and see how warm it is in the garage.

This looks to be the simplest method of watching water/mash temps. Did you have to modify the probe in any way to be water proof or is everything ready to go right out of the box?

Out of curiosity, are you referring to the Traceable Waterproof Thermometer??? I just found out the same thing. Fortunately they sent me a new one, and I wont leave it in the mash and/or the boil next time.

Yep, that's the one. My bitching and moaning also resulted in the following disclaimer being put on the product page in red font...

"Note: The cord can only withstand temperatures of 122 degrees. This cord should not be submerged in liquids higher than 122 degrees."


They still say that it's good for brewing, though...even though when I spoke to the woman at Control Company, who makes that thermometer, she said that it's actually not good for brewing at all. Meh. At least I got that disclaimer on there. I still can't believe that douchie tech support guy tried to say that it's "common sense" that the sheathing is only rated to 122f. :cross:

No, that probe that I got is waterproof (I think all type K probes are, actually...it's just a loop, one wire down, u-turn at the end, one wire coming back up), and is also heatproof up to like 500f or some crap. The indicator is water-resistant. I didn't mod anything, except for the tiny hole I drilled in my cooler lid to run the probe through.

Wow, idiots. A guy there told me that only the metal probe part is waterproof. Uh, yeah well no sh*t, its a piece of metal. With that kind of logic every thermometer is waterproof! I also griped that nowhere did I see it stating that the cable would not work up to 150* (mash temps). I admit I shouldnt have used it to check my wort temps (from boiling on down), but for crissake it should be able to withstand 150*F for that price.

I wonder if it was the same douchewhistler that I talked to. Argued with that ******* for 15 minutes...he kept telling me that everyone knows that the cable isn't rated for above 122f. How? Uh, because, it's common sense. Really? So the guy essentially called me an idiot for not knowing a piece of information that is not published anywhere. I was hot, man...so finally I asked him what he was going to be able to do for me, and he said "all I can do is tell you not to submerge the probe in the future". I hung up, wrote a scathing email to their customer service dept., and a nice lady called me a few days later and apologized profusely, and refunded my money for both failed units.

Some people should just not be on the "customer service" side of operations, you know?
 
Dude that sucks, I hate experiences/service like that. But they were much nicer on me. I emailed them and told them that I was having erratic readings, I replaced the battery but it made no difference. They asked my application. I told them mashing @ 150F. They told me it cant do that. I told them that it didnt state anything about the cables limitations.

well, I found the email, here is what he said in the last exchange. The tone of the email exchange was courteous and professional. And I was very happy they replaced the unit. However, I am not happy that it cannot do what I want it to. I want to leave it in mash and leave it in the cooling wort. This was very recent, like 2 weeks ago (I just got the replacement on Friday). You must have wore him out and he was easier on me!

Thank you for purchasing Control Company products.

Well, yeah...that's much better than what I experienced, but then, that's probably because your tech support rep is also one of my favorite musicians (must be his second job). :D

I'm kind of curious as to the use of the thermometer in the cooler lid (MT?). Once the cooler lid is closed, you're just using the thermometer just to watch the temps...do you do any adjustments based on the temp or is just to confirm your process is done correctly?

I'd like to use the thermometer in heating up my strike water, any problems with this in a SS pot? Opening the lid and sticking in a prob and waiting for it to measure the temp sucks, I'd rather keep a constant watch to know exactly when I hit my desired temps. Should I buy a 2nd K probe, one for the heating and one for the cooler to watch the MT?

Thanks!
 
I have this traceable model and I am completely happy with it. It's a bargain at $38.46. The replaceable type "k" thermocouple is included as is a carrying case"

http://www.coleparmer.com/catalog/product_view.asp?sku=9121045

I've been using it for more than a year and find it to be rugged, reliable and very accurate. It is also user calibratable, but have never found it to be out of calibration. It will accept any "k" type probe, but the included one serves my purposes just fine.
 
Thermoworks really backs up their warranty as well. I had an older model Thermapen go bad on me. Thermoworks was very nice about it, offered me a few different repair/replacement options and was just easy to work with. I have since received and brewed with the MTC and strongly recommend it to any brewer. You simply cannot beat the quality of the product and the quality of the support behind it.
 
I'm buying a thermapen. I'm not even biting on the sale price for the old ones, I am going for the splash proof, 0.1*F resolution, shiny new bulletproof one.
 
So a couple of hours after I ordered my Cole-Parmer thermoprobe, I look at ebay and here is what I found for sale in abundant quantities for a lot less $ (2nd photo). Very striking similarities don't ya think? I'm sure I'll get better customer service from Cole-Parmer since they are in IL and not Hong Kong. I'm seeing $28 including shipping on eeeebay

Similar yes; identical no. On the plus side for the Hong Kong version is that it can monitor two probes at the same time and it includes two probes. I also saw those on Ebay. I am curious about this note they put in following the specs:

"Buyers – Please Note:

Import duties, taxes and charges are not included in the item price or shipping charges. These charges are the buyer's responsibility.
Please check with your country's customs office to determine what these additional costs will be prior to bidding/buying."

I wonder if any of that applies to the USA buyers. I doubt it.

The biggest difference that I can see between the two is that the Cole Parmer model is a "Traceable", meaning it is lab calibrated and certified. The Hong Cong model does not seem to be. I think they are both made in China as is almost everything these days.

The Hong Kong mode sure does have a hot price. I would buy one if I didn't already have the Cole Parmer unit. Might buy one anyway at that price just to have a backup. Might just buy two of them.
 
+1 to Thermapen. I scored one as a gift, used it yesterday and the brew was much less stessful for hitting temps. It really did smooth things out. It's pricey, and I had hesitated to buy one for myself, but now that I have it, I'll encourage others. And I should have bought it a year ago.
