Hands On: ThermoWorks RT600C Super Fast Thermometer – Accuracy and Response Time Tests

Note: This is a comprehensive update and expansion of a June 2012 review that was posted on Homebrew Finds.  It includes additional photos, accuracy and response time tests and information about recent updates to the RT600C thermometer.
 
 
I’ve owned and used ThermoWorks’ Super Fast RT600C as a homebrewing thermometer since 2011.  It’s very accurate, has a super fast response time and has a great set of features.  Because of my work on Homebrew Finds, I have a large number of thermometers.  I propose that, considering it’s price point, the RT600C is one of the best thermometers available for homebrewing.
 
The Thermometer along with the included Pocket Clip.
 
The RT600C has a good sized probe (4.9″) but only 1/4″ needs to be submerged to get a reading.

 The battery door includes and o-ring

 

The RT600C is waterproof.  Not just splash proof or “kind of waterproof”, it’s waterproof.  IP65 rated to be exact.  That means you can put this in a dishwasher – up to 190 deg F.  To illustrate I’ve submerged it in the Top Find Rubbermaid Commercial Brew Day Pitcher (Review).

Accuracy:

Testing with ice water in my Lifeline Vacuum Insulated Stainless Growler (Review).  The RT600C reads a perfect… 32 deg F.

 

Still 32 deg F, side by side with my ThermoWorks Thermapen (Review)

 

I’ve experienced different boiling temperature on different days using the same equipment and testing methods.  Boiling temperature is a moving target.  It is based on elevation and atmospheric conditions.  The day of this test, boiling point was a consistent 211.8 deg F as read by my highly accurate Thermapen.
 
The RT600C reads 211.5 deg F.  It’s reading to .3 deg F low.  Well within it’s stated accuracy of +- .9 deg F.
 
Response Time:

This video shows a response time test using the RT600C.  I’m counting the start of the test as right when the metal basket hits the water. The probe of the thermometer is submerged at 1 second into the video. It levels out at 139.6 deg F at 7.85 seconds. That’s a response time of 6.85 seconds. For .1 deg F resolution, that’s a great response time. For comparison, I’ve tested the Thermapen (Review) and gotten a response time of 5.4 seconds (at 130.4 deg F).  The Thermapen is an amazing thermometer, but it’s also about 5 times the cost.

Auto Shut Off (now included)

In the original version of this review I noted that the RT600C does not have an auto off feature.  Not a huge deal if your version (like mine) doesn’t have auto off.  What you can do is… shut it off :).  If you do forget, the batteries are relatively inexpensive.  Update: ThermoWorks has changed the design.  The RT600C now includes and auto-off feature.  If for some reason you wanted a version that has no auto off, that’s found in the RT600B.  That one stays on like the RT600C used to.  Not very helpful for homebrewers.  I think that’s generally used by food service professionals trying to test dishwasher temperatures and such.

Some of the RT600C’s features:

  • Waterproof.  In fact it is dishwasher safe up to 190 degrees F.
  • Has a super fast read time- 5-6 seconds.  IP65 rating.
  • Accuracy to ±0.9°F (±0.5°C)
  • C/°F switchable
  • Only requires 1/4″ of the probe to be submerged to get a reading
  • Has a .1 degree resolution
  • Records Minimum and Maximum Temperatures.  You can use this to monitor serving and fermentation temps.
  • Long Battery Life – up to 5,000 hours of continuous use
  • NSF Certified
  • Tough Commercial Design
  • Manufactured by Thermoworks.  Warranty - The RT600C comes with a one-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.

 

I purchased my RT600C back in October of 2011.  As of this update (June 2014) the same unit continues to be an amazing thermometer.


With years of practical use in homebrewing and beyond, I can recommend the RT600C (ThermoWorks - Amazon) as a great homebrewing thermometer.  Considering the features, performance and cost, this is arguably one of the best values for your money.  Along those lines, the RT600C continues to be one of our Top Find selections.

Completely submerged.  Note: The manual explicitly says not to do this.  Guess what?  I did it!  I completely submerged this thermometer for version 1 of this review sometime around November of 2012.  The thermometer has gotten plenty wet since then and is still performing like a champ.  I’m not suggesting that you completely submerge yours.  You should follow the manual’s instructions.  I am saying, mine has held up to this type of treatment.

Accuracy:

I’ve experienced different boiling temperature on different days using the same equipment and testing methods.  Boiling temperature is a moving target.  It is based on elevation and atmospheric conditions.  The day of this test, boiling point was a consistent 211.8 deg F as read by my highly accurate Thermapen.


The CDN DTQ450X reads 211.6 deg F.  It’s reading to .2 deg F low.  Well within it’s stated accuracy of +- 2 deg F.  Practically speaking, for our needs, this is right on.

Ice water is a more reliable reference point.  Here is the CDN DTQ450X head to head with the Thermapen.  As you can see, the Thermapen reads right at 32 deg F.  The CDN DTQ450X reads 32.9 deg F.  Again, well within it’s stated 2 deg F range.  This is a good result.  Not great, but good.  That fact that it is more accurate at the higher range bodes well for homebrewers.  We’re much closer to that end of the spectrum for most of the things we’re doing.

Response Times:

 

This video shows a response time test using the CDN DTQ450X.  I tried to do this with water that was around mash temperature.  I’m counting the start of the test as right when the metal basket hits the water.  The probe of the thermometer is submerged at 2.28 seconds into the video.  It levels out at 138.3 deg F at 5.7 seconds.  That’s a response time of… 3.42 seconds.  For .1 deg F resolution, that’s a great response time.  In fact, it’s 1.98 seconds faster than a similar test I completed on my review of ThermoWorks Thermapen.

Bottom Line:
 
I’ve used the CDN DTQ450X since October of 2012.  This same unit continues to look and function well.  This thermometer is one of our Top Finds and it’s also a key component of my Brew Day Box.  It displays very good accuracy, well within specifications, and it has a very, very good response time.  If you’re looking for a thermometer for homebrewing and general use this is an excellent choice that I can recommend based on experience..
