Beware of thermometers with probe: unreliable models !

  • 8

Hello,

After one month of usage, my thermometer with probe started to give random results.

I was very surprised as it did work very well for the month I owned it. So I looked at user feedbacks on amazon.fr, amazon.co.uk and amazon.com for my model (eKitch brand) and I saw that I was not alone in that case.

But more interestingly, I noticed that many makes and models suffered from abnormal rates of random failures that looked similar to mine.

See for instance:

"Taylor 1470 Digital Cooking Thermometer/Timer"
http://www.amazon.com/Taylor-1470-Dig...

"CDN Digital Programmable Probe Thermometer"
http://www.amazon.com/CDN-Digital-Pro...

"ThermoWorks The Original Cooking Thermometer"
http://www.amazon.com/ThermoWorks-Ori...

All these models seem to share the same Achille"'s heel: the probe itself.
So far, I haven't figured out what makes it fail, but until then, if you shop for an oven thermometer with probe (a tool that I otherwise find extremely useful), skip those models with that sort of probe, it's junk.

  1. I've had that Taylor model for a number of years - more than I recall - without probe failure. However I do treat the probe and its cable with great care - not bending it sharply, pinching it, or getting it wet (beyond inserting the probe in the item I am measuring.

    A one piece thermometer is more robust, just not as convenient for tracking the temperature of items in the oven.

      Hello Paul,

      I did treat my probe with the same care, but it failed nevertheless. I don't know if it's due to the fact I left a little bit of water in the oven, trying to increase humidity by creating vapor. But no liquid water went in the probe itself.

    2. I've had a few like those, untill I bought a weber remote , I've had it 7yrs, use it at least twice a week in the oven, in the bbq, winter, summer, rain snow never failed. I'll add the batteries are 4yrs old and I just ran it for 9hrs on sunday doing a pulled pork, and it's still going strong.

      I also picked one of these up to moniter the inside temp of my smoker(or bbq) and the second probe I can use in my food, or moniter 2 zones in the smoker(or bbq) and I can check the accuracy of any thermometer I have.

      There's also a maverick that i've heard a lot of good reviews about as well

        Hello Dave,

        Unfortunately, it's not (only) a price problem, I believe the electronics are fine. But I believe you were lucky.
        I can see on the photos that these two models work with the same kind of unreliable probe, and both of them suffer from the same sort of reliability problems, as is confirmed by amazon user feedbacks.
        For the Weber:
        http://www.amazon.com/Weber-6438-Prof...

        For the Maverick:
        http://www.amazon.com/Maverick-Wirele...

        Basically, it seems to me that about 1/3rd to 1/2 of the user feedbacks are negative, i.e they fail in the first 6 months. Not counting those that fails after one year and are not reported. There really seems to be a quality issue with the probes, or more probably a design issue, and nobody seems to be doing anything about it.
        Now I'm looking for an affordable professional digital thermometer with a K-type probe that goes in the oven, or a cooking thermometer with a different kind of probe. Or if I can't find it, a simple non-digital oven thermometer.

      2. I would go with something like this:
        http://www.amazon.com/Digital-k-type-...

        I tend to trust measurement instruments more than consumer stuff, as they have to pass tighter tolerance. Unfortunately, there doesn't seem to be any K-type needle probe that goes in the oven.

          If you feel it's worth the $100 US, these are quite accurate http://www.thermoworks.com/products/h... and you can purchase a probe with a metal jacket that will take up to 350°C and is heavy duty for another $65 US.

          The obvious advantage to this type instrument is that the probes, and there are many from which to chose, are replaceable. We use Fluke at work but the hand unit never dies, it's the probes, and having them replaceable is a great feature.

            The second link I put up is a k type, also it is the one I have. If you buy the k type you linked to you will need to purchase your probes separately, as it ships with just the wires. And I agree with you on consumer models which is why I went with 140$ commercial, plus probes My link didn't work so mine is similar to this http://www.amprobe-direct.com/shop/it... The amount of probes available is staggering if you know where to look http://www.amprobe-direct.com/shop/it... http://search.digikey.com/scripts/DkS... If you can get your old probe apart, you can just slide the wire with no probe down into the old one and secure it , it will work fine
            Here's an easier link to probes

              Thank you for your answer, but this is a bit out of my budget. I think I'll stick with an oven thermometer and a standard cooking thermometer. It's far less convenient, but I guess there is not much alternative at the moment.
