I have the same Thermoworks high temp waterproof probe that sniperd has but I have the Therma K thermometer.

I have not replaced the batteries in my ThermaK yet and it is still going strong. The 39" waterproof temperature probe still looks like new. My best guess on how many batches would be about 20 - 25 in the year since I wrote the above post.

EDIT: I went back through my notes and it has been 20 batches.
 
Just a follow up on a post from a long long time ago :)

We've got 3 of these now:
http://thermoworks.com/products/handheld/mtc.html
The MTC model.

Two with the long probes and one with the short. In 2 years we have replaced two batteries and these things are ROCK SOLID. The only very small issue we have had is it is possible to pull on the probe too hard and make the connections pull out, then you just get crazy readings. Stuff like -100F then 450F. So you know something is wrong. It's easy to fix with a screw driver by opening the probe, pushing the wire back in, and closing up the probe.

It is a very solid product though, we've used it in the winter, summer, snow and rain. Dropped the handheld part on the ground and dropped it into water and it works great. We've gotten the probe cable pretty close to the flame from the burner and it was ok (got a little black but caught it before the plastic melted).

In any event, these things are made to last and are money well spent.

It looks like these are the best investment of the group with them being pretty accurate. I was planning on having two probes, one for the mash tun and one for the boil kettle. Now, do you submerge the probe in the boil or just above the boil? I just want to make sure I'm getting accurate readings on these.

Thanks for the updates.
 
You can throw the probe (the long yellow cable) directly into the water or mash tun. One of the uses for this thing is to measure and calibrate an oven or a dishwasher, so you know it can withstand a beating! The prob plugs into one of these:

http://thermoworks.com/products/handheld/mtc.html

Since we own 3 of these we have done tests of putting all 3 into boiling water and they all read within 1 degree of each other, so they are very accurate.

The only things to keep in mind is if the probe is touching the bottom of the kettle it might read 1 or 2 degrees higher as it could be picking up the temp of the metal, so we have noticed during boil if we throw a prob in it will read 213 or 214 sometimes if the prob is laying on the bottom.

Also in your mash tun you'll notice that the edges of the mash tun are cooler than the middle. We'll.. that's what we have found to be the case. Kind of neat.

On probably brew 60 with these things, and I'd say you have to replace they battery about every 18 months? They are little cheap watch batteries that you can get anywhere for a $1 or so.

It's a great tool, one of the best things we have bought for brewing.
 
I also use type K thermocouples, they are cheap and really accurate. You can get long probes and reader on the amazons for like $20 total.
 
I too have a thermoworks MTC with a probe and then the yellow wire that just sits in the mash tun. It works great but the thermapen does take slightly faster readings from the probe, 1 second vs 2 seconds...

For brewing I think the MTC is the way to go.
 
Thanks for the feedback, I will grab one of these with two probes; one for the mash tun and one for the kettle
 
Great read. I was in the market for getting a nice probe. Had been looking at the Thermopen as it seems highly recommended. Stuck with the company but went the MTC route as many here have suggested. Got the MTC, the recommended cable/probe along with a regular probe that is the same one on the Thermopen and gives faster readings then cable version. Nice being able to keep one main component (MTC) and multiple options with other probes without dumping a large chunk for another dedicated unit.
 
Thanks for the suggestions on a digital thermometer. Just a heads up (maybe they always do this but) the website suggested is having a 15% off sale through the end of today and only 3.99 shipping so I was able to get the thermometer and probe suggested for around $50. Im glad i finally pulled the trigger on a decent thermometer after ruining many cheap thermometers from the big box stores.
 
I use a Thermoworks ChefAlarm. Very accurate, calibratable, a little slower than the Thermapen, but has timers and alarms and heat proof remote probe. I upgraded to the 12" professional probe.

And I have a cheaper Taylor hand held that is well constructed, and it's about 1° C different than the ChefAlarm. I think it's called a weekend warrior or something and is like $20-ish. Its been through hell and still works great.
 
I currently have the Weber one you mention above, which is the reason I'm currently reading this thread: because it's junk and I need a new reliable one. I just found out mine is 5-10 degrees off, depending on how the thermometer is feeling at any particular moment. I've had mine for under a year...I don't know if it's always been off, but I just noticed it now.

I thinking I'm going to get one of the lower cost Thermoworks mentioned in one of the earlier replies.
 
Lol. That sounds great. Maybe that's why it was on the clearance rack at Walmart
 
Update, 100+ batches, over 5 years later and the are still working fine. Had to change the batteries a few times but rock solid.
 
I've been using an analog thermometer for the longest time and recently purchased one of these from Thermoworks: https://www.thermoworks.com/RT301WA

It's a decent thermometer and I like that it can be hot/cold calibrated if the reading ever goes off. But here's the thing... I compared it with my 15 year old standard kitchen thermometer that cost me just a few dollars and it is just as accurate. Both take 3-6 seconds and both read within a fraction of a degree of each other. I suppose at least I know my old cheapy thermometer is accurate and now I have two to work with.
 
Another vote for Thermoworks Thermapen. I do a lot of grilling/smoking and cooking in the kitchen too, so it was a great investment.
 
I have a CDN thermometer with a wired probe that I have beat the snot out of and is still working. I've dropped it in my mash tun, spilled all sorts of crap on it. Just keeps going. Probably not as fast as the thermopen, but it's only $30ish.
 
I'm a little late to contribute here but I've bought one from the company that makes thermopen:

Professional Thermometers from the Temperature Experts | ThermoWorks

I didn't go with the pen because I wanted one like the cheap-o kitchen ones that I could toss a prob in. So my brewing friend and I each got:

Shopping
It's the MTC model

and then we each got the long waterproof probe with it:

Wire Type K Probes | ThermoWorks
It's the Model: 113-372/373/375-T

It's almost a little too long but I didn't want to end up too short. Not much difference in price for the long one anyways.

I called them up to ask about if this works for me in a mash tun. I asked my sales person if this was the correct thing to order for an all grain brewer with grain, 170 degree, sit in water, etc. I heard her ask the head sales guy and I could over heard him say "Yep, that is the combo the brewers use who put it into their big grain tub, no problem". The probe can be used to test the temp in a dish washer and the hand held part is mostly water proof. We've made 30 batches of beer over the last year with it, rain or shine, no problems and the battery is still fine. I suspect the handheld part into boiling water it wouldn't turn out so well but I've certainly gotten it wet. I would highly recommend it.

I got sick of using the $15 kitchen ones from walmart to have them die or be off by 10 degrees after 2 batches. This is money well spent IMO. Hopefully this helps somebody else.

Just an update 8 years later. Dropped on of them right into the mash while stirring this week. Tried to grab with bares hands OUCH. Put a rubber glove on fast, grabbed it. Still working! These things are great.
 
I have several thermometers from ThermoWorks. I like the Thermapen MK4. It has AAA batteries instead of the little coin battery that some of the others use. I always have triple a's around. I also have a Dot thermometer from them. I use both for cooking and beer making.
 
fwiw, I have a first gen Thermapen (recently re-cased) and a Mk4. I bought the first one for my BBQ needs, as well as just cooking everything perfectly, and I almost never use either for brewing - just checking starters now.

What I do use - a lot every brew day - is this: ThermoWorks RT610B-24 Long-Stem Digital Thermometers

From reading grain temp while still in the buckets, checking settled mash temp, checking hlt temp, checking kettle temp when dropping to hop whirlpool temp, this long stem digital is a great fit to my brewing needs...

Cheers!
 
I have a fluke IR thermometer that I love and it's possible to plug a type K thermocouple into it so I've got those taped all over the place with dangling connectors. There's nothing more instant than infrared!

That's awesome. I have the Therma-Waterproof with a really long handled probe (12"?) and another Wire probe made for testing commercial dishwashers. That one is what I leave in the mash, it's proven to be a great tool.

I also got the Silicone cover with the kickstand and the magnet. I use the magnet all the time, sticking it to something nearby while I take temps. I think it's a must have accessory for these thermometers.
 
I come from the competition BBQ community and very aware of the virtues of a thermapen. There are three things that make the thermapen the gold standard. For BBQ folks, the probe since at some point we ignore temperature and go with feel. The probe does that for us. So that is not a factor in brewing.

the other two are speed and accuracy. I have. A number of probe thermometers and my cheapest $16 one is dead on accurate (calibrating a calibratable thermometer is very easy with ice and water) go figure. It’s also water proof etc. so for reading temp it’s as accurate as the expensive thermapen.

So that leaves time. The real advantage of the thermapen is that it will read temperature in 1 sec (as per the manufacturer) Is that critical in brewing. For BBQ folks, an open pit is not desired. It changes increases the air flow which which drops the pit temp initially, but then the fanned embers spike up the pit temp. Thus a fast thermometer is desired. I have a Maverick which is lightening fast but it’s off by a degree. I cannot calibrate it. But, I also know one degree is useless, why....

odds are you will never know the exact temperature of water or mash. This is because the water near your hearing element will be hotter than the water near the top. In fact the Anvil Foundry uses a formula to adjust what the probe says to account for this.

Now, a thermapen is like a Porsche. Not only is it high performance and more than you will ever need, it is recognizable design that projects excellence.

Regardless, Check any thermometer you use with ice water. They will all read temp within 5 seconds, so give the water a good stir to blend it up and dip the probe and don’t sweat a degree or two.
