Question: Does anybody know exactly how large the probe is (how long is the part that actually measures the temperature)?
Document: This is as fast, or faster, than an analog thermometer and doesn't get in my way. The probe is smaller than an analog thermometer's probe, which is part of the reason it reads so quickly, but it also means I'm not putting a large hole in a loaf of bread, which is a plus.Other people have been impressed by my new thermometer - the students in the baking classes I've taught since getting the thermometer have wanted to know what kind of thermometer that was.
This has been doing exactly what it is advertised to do since I got it. I don't know how long the battery will last, but so far so good; no complaints.
That is where this truly instant read thermometer comes in. It determines the temperature quickly and accurately. Within a few seconds you can actually see the temperature rising because of the cooking process, not because the thermometer is still adjusting! This thermometer has become an essential tool in my kitchen arsenal that I don't know how I lived apart from before. (I guess I used to have a lot of knife slits into whatever I was cooking because apparently I liked dry cuts of meat).
I've used all kinds of instant-read thermometers before picking this one up. It's quick to get a temperature (5-6 sec), comes with a nice case, and is high-quality. Now, I can't recommend it enough!Pro's:-It's fairly long, meaning it's easy to use on the grill, in pans where you are pan-searing, or with large cuts (like roast)-The case provides a nice level of protection for it.
Temperature reads are quick, accurate and does exactly as promised. Also the protective cover can be placed on the back of the unit to extend the probe into hot liquids so your hands can avoid the steam.
This thermometer is so much better then the one I had. It is easy to use the probe is smaller and does not make a large hole. It reads much faster and seems to be better at giving me a real temperature reading. Glad I made this purchase
Without ranting about all the thermometers I have. I am a grilling smoking fool. Case closed.Mine reads and stabilizes at 5 seconds every time. The 1 second faster thermometer that you can buy for around $80 is 2 seconds faster at best.If this one fit in a pocket it would be the only one I use, I am not sure why they made the probe so long for, I don't know of anything you would ever cook that you would need to penetrate 7" to the center.
The best part of the ThermoWorks thermometer for me is the face display. It is super fast just as advertised and I have had no trouble with turning it off. Too make sure it is off, I place it into a clear glass jar on the counter top in my kitchen work area. I know from experience that placing a thermometer into a kitchen drawer makes it difficult for me to keep track of them. I would recommend the Digital Poket Thermometer to anyone who needs a super fast an accurate thermometer.
Used it on my prime rib at Christmas and my result was exactly what I wanted it to be.I also used the thermometer to monitor my water temperatures coming out of the tap when we had the really cold snap. I did this to make certain that my water lines were not going to freeze. The unit's accuracy was very useful. It's nice to know that I'm not going to have frozen water lines!
This is my 3rd digital thermometer, bought to replace two others that failed. It's very quick, accurate, and I love the long, thin probe, which is much easier to insert into meat. I cook by temperature to make sure I don't undercook or overcook meats, and this has been great for that purpose.
Answer: The probe is probably around 6 inches. From what I could tell it is the first 1/2 inch to 1 inch that registered the temp.
