The RT600C digital pocket thermometer has been Rated #1 by a leading Cook's Magazine. This ThermoWorks digital pocket thermometer reads temperatures in just 5 seconds. A super-fast digital thermometer, the RT600C is currently in use in thousands of restaurants, food plants, labs and is carried by health inspectors world-wide. It's the perfect instant-read thermometer, and the affordable choice for home or commercial use.

  • Improved Accuracy

    The RT600C is a super accurate pocket thermometer that's been upgraded to ±0.9°F - up to 212°F. This accuracy is only found in professional thermometers. The RT600C has been thoroughly tested against NIST-traceable standards.


    The RT600C digital pocket thermometer is faster than any other thermometer in this price range! The reduced tip is only 1/16" diameter and complies with USDA meat thermometer requirements. Fully speed-tested in the ThermoWorks Standards Lab to ensure the thermometer reaches within 1°F of the final temperature in only 5-6 seconds (at any temperature in the range).

    Longer Battery Life_

    The RT600C digital pocket thermometer uses a reliable CR2032 battery with circuit improvements to reliably allow for 5,000 hours of continuous thermometer use between battery changes.

    Max/Min Function

    The RT600C digital pocket thermometer saves the highest and lowest temperatures since your last reset. The thermometer is great for checking fridge or freezer temps. When you pull your roast or turkey from the oven, insert the instant-read thermometer and leave it while the meat rests so you know the highest temperature reading. Max/Min records the high and low over a period of up to 1 hour, then the auto-off shuts the unit down. Max/Min will start with new values when the thermometer is turned back on.

    Auto-Off after 1 Hour

    If left on, the RT600C digital pocket thermometer will automatically shut down after 1 hour; still long enough to make the Max/Min function useful. What good is Max/Min memory if the thermometer turns off too soon? If you need to record Max/Min for longer than 1 hour, see the RT600B, that does not have an Auto-Off feature, for recording over longer periods.

    Tough Commercial Design_

    The RT600C digital pocket thermometer has been designed with minimal food and grime traps. Rubberized button panels are sealed and withstand temperatures to 190°F. No welded or braised joints on the thermometer probe that would shelter microbes or create likely breakage points. The RT600C is designed to survive short term, shallow immersion - you can wash the thermometer under the tap or use it with wet hands. Rated to IP65. NSF approved for use in commercial food applications.


    The RT600C comes with a two-year coverage on material and workmanship including any failure in the thermometer circuit. Includes online, email and phone access to the ThermoWorks technical service group.

RT600C Works Great
Received as a Fathers Day Gift for use with my new BBQ grill. Being an old engineer, The first thing I did was check accuracy. Using an ice water bath it read 32.0 degrees. Can't get better than that. Using two medical thermometers at 95.8 as a reference, the RT600C read 95.6. Fantastic. Now I use it for everything when I need to know a temperature. The tip is small and slides into meat or fowl easily. The Min-Max feature lets you stick the probe in for 5 or 6 seconds, pull it out, hit the button and read the meat temperature. No more sticking your head over a hot grill. This is a fantastic thermometer you just can't go wrong with.

Best affordable thermometer
I have had this thermometer for over a year. For the price, its speed and precision have no comparison. In addition, this company has amazing customer service, I highly recommend the buy.

I have no idea how I cooked before I got this! I have been cooking and baking for - oh dear - 40+ years. Yes, results were sometimes inconsistent, but I filed it under "what can you do?" Well, here's what you can do: Get one of these. My husband, very politely and sweetly, finally told me that my chicken was consistently overdone - I was afraid of undercooking it and so it was tough and dry. Now it is *perfect*. Same with bread, other baking, other meats, everything. I love it. It's like a little yellow magic wand.

High quality
I have used a few other thermometers including a "quick read" digital thermometer from another large online seller. It was about the same price and took 20 seconds to get to temperature. And was about 10 degrees Fahrenheit off of both boiling and ice water. This was perfect and my first meal was perfectly cooked. I'll update after some use.

Fantastic Thermometer
I work in a laboratory where temperature is one of most common measurements. I've tried thermometers from other large lab equipment suppliers that are about the same price or more and they are both less accurate and take more time to get a reading. We check our thermometers prior to every test. For ice, its almost always 32.0F, in general its almost never more than 0.2F off. Have not found a better thermometer for the money. Its not just cooking grade, for basic measurements, its lab grade.

Grilled to perfection
These thermometers work so well we purchased six of them and gave them as gifts to our children and friends.

I use it when grilling and smoking ,. It takes all the guessing away, everything is cooked just the way I want it.

The only improvement which could make it better is a lighted background for night time grilling.

Satisfied Calf Feeder
I feed calves and use this thermometer twice a day to mix milk - it reads fast, reads accurately and lasts! Thank you for a quality product that doesn';t break the bank and makes my life so much easier!

I have only had this unit for 1 month but so far I love it. It is accurate, convenient, and handy with the pocket clip. I saw this in the Consumer Reports as the best buy and I do agree.

Game Changer!
I had no idea how far the gap was between a generic thermometer and a high quality professional one was. This was meant to be an upgrade and has instead changed the game. I use this for brewing beer and it has seriously made such a huge improvement to my process that I am shocked.
