Extech TM55 Food Thermometer Review

post #1 of 12
Thread Starter 
Recently I ordered an Extech TM55 thermometer to use at work for measuring the temperature of some chemicals I use for calibration. I had 2 reasons for doing this; 1, I needed to measure temperature in my lab, and 2, I wanted to see how the Extech TM55 worked before I ordered one for my cooking use.

Since I knew I was going to be at home this week, assisting my bride after her back fusion, I ordered last week so it would be here today for testing.

Here is a link to the specs on the Extech TM55: http://www.smokingmeatforums.com/t/237568/extech-tm55-anyone-tried-it

So, I got the thermometer this morning and set about checking the accuracy.

It came in a big box, but the actual package for the thermometer was just so so.


After opening it up, I removed the battery tab, and powered it up. To power up, you simply fold out the probe, kind of like another thermo out there.

After opening the probe, the temperature read pretty close to what the temp was in my kitchen, warm since I was cooking at the time.



I filled a plastic cup with ice, sat the probe into the ice, and waited for the temp to stabilize. It took about 6 seconds by my count. The temp stabilized at 31.1 degrees. Not too bad.


I pulled the probe out of the ice, let it get back to room temp, and then put the probe into boiling water. 210.5 degrees was shown in about 6 seconds. That's basically right on the money for my location.




So, thus far, I'm impressed with the response time, recovery time, and accuracy. The proof will be in the meat testing. That will have to wait, raining here today. But it'll happen this week for sure!

Sounds impressive so far.  What is the cost? How does the cost compare with others such as the Thermapen?

I'm glad you got it. Something other than an expensive Thermapen with no lifetime guarantee. That's why I bought the Thermowand by Lavatools which. resembles yours. It's the best $25, four second, accurate lifetime guaranteed therm purchase I've made.

Thanks for the review, CB!

I checked this one on Amazon (prime) at ~$35.00. Text says it's dishwasher safe (but I don't know if I'd test it). I didn't see anything about a warranty or lifetime guaranty, though.

Looks like you found a great alternative to the Thermo- thing.

I figured for 35 bucks, it was worth a shot. Like I said though, the proof will be in probing some Q later this week.

Looks virtually identical to the Thermowand, which is $10 cheaper.

Probably is the same thing, just branded differently in a Chinese sweat shop. biggrin.gif

For $15 more you could've gotten the Javelin PRO from Lavatools, who probably made the green one you have.

Good purchase nonetheless, they're great little thermometers.

Yep, but like I said above, they are probably all made in the same Chinese shop, just branded differently.

I'm mainly looking for a thermo that is decent in read time, fairly accurate, and affordable to folks that are just getting started.

I have a Thermapen and several other hand type thermometers, but I seldom use them since I have the remote probes that I build. About the only time I use a hand type is when I'm grilling a steak, or I think my remote probe is acting goofy.

Your right!  All are Chinese or UK.  ETI, Ltd. (Electronic Temperature Instruments,  Ltd) in Worthing England manufactures the Thermapen.  Thermoworks in Utah markets and honors warranty and  fixes out of warranty Thermapens etc @ $20 a pop. Maybe that's how they came up with the Thermopop. JK DaRicksta, because they're not guaranteed for life.   CDN (Components Design Northwest ) is Oregon  based as well as Oregon Scientific.  Maverick is New Jersey.  None are all Manufactured/assembled in the USA, so experiment.  Within the last two years we have extremely accurate therms to hopefully bring the Thermapen to a competitive price.  Kinda like a name brand drug that has the same ingredients as a generic. I would cherish a Thermapen, If  I didn't have to buy it.
