@derobert Yes. I have one. But's a small dinky one.
I purchased it because our fridge was having issues. But I would like a better, more "professional" one.
Apparently the auto-defrost function was mishehaving. So it wasn't letting the fridge cool properly. Supposedly it is fixed now, but I'd like to check it out.
I have a couple. I have two wireless fridge/freezer thermometers at home, with alarms. They... work, though are crappy in various ways. Got a one that sits in the fridge (so you can only read it when the fridge is open) and put it in the fridge here at work, that one is much nicer
Huh, had two simultaneous SSH brute-force attacks using the same username from a DigitalOcean address and a Malaysian address. They arrived a second apart.
One problem with a thermometer in the fridge is that the minute you take it out the temperature starts going up. And the dinky one I have doesn't have a freeze display option.
Mainly its crappy that the buttons on it are way over-sensitive. Try to press the alarm enable/disable button and watch it take it as five button presses. Just keep trying until it gets in the state you want. Same with e.g., the target temperature adjustment, which is annoying. But thankfully you only need to do that adjustment once in a while (after replacing batteries).
@derobert Would it work as a fridge thermometer? Like I said, no range is given. Of course I could check the product listing on the manufacturers web site.
You wouldn't want to put it in the freezer. Putting the probe in would be fine (and even if your freezer somehow runs below -50, too low just won't read — I doubt it'd damage the probe)
@FaheemMitha yes, you could do that. Or just have it sit on top of the fridge, and snake the cable in. Note that it's not going to be an easy cable to snake. It's got a braided steel jacket.
Unusually for an import, the price isn't grossly inflated here. It's really annoying when you are paying USD 20, 30 or even 40 for something that costs USD 10 in the US.
@derobert From outside the fridge that doesn't sound appealing. Does it have an option to freeze the display? And does it have a remote? The latter, I suppose, is unlikely.
@derobert Not really designed for a fridge, then?
Anything similar for the fridge? A lot of the fridge thermometers look really sucky.
As @Jesse_b mentions, the ones with probes on a wire are normally intended to either put through the door for temporary installation or alternatively drilled through the fridge for permanent install.
@FaheemMitha it goes from flat (fully open) to maybe a 90° angle. It doesn't fold closed. Its so that it can be angled nicely when its sitting on a counter.
@derobert That's good to know. As you may have seen. the Indian listing only has one review. Which is relatively literate, by Indian standards. But no really enough to base a decision on.
@PrabhjotSingh Incredibly unlikely. Even Gilles doesn't know everything.
Actually, @Fabby said at one point not to bother with fridge thermometers , because they suck. Just get a good general thermometer. He might have a point.
@FaheemMitha Is there even another company that specializes in thermometers? And for home use, not say chemistry lab? I can think of some companies that make weather instruments... but they all put out crap too...
@derobert I have no idea. There are tons of thermometers listed in Amazon US. Less on Amazon India, but still quite a lot. How can one tell which of these are specialists?
Calibration means someone took that particular thermometer into a calibration lab and measured & recorded exactly how close it is, then you get that along with the thermometer. Traceable means that calibration lab's temperature standard can be traced back to a standard maintained by a national standards lab (like NIST).
coleparmer.in/i/… e.g., if you order that, before shipping that particular thermometer to you, someone has tested it in a calibration lab at 0°C and 50°C to make sure it's within 0.2°C. And sends you certification of that.
That adds a lot of cost.
(I have no idea if they'll sell it to you uncalibrated or not. That'd be a fair bit cheaper. You could then measure it yourself in an ice bath, which would be close enough for anything outside a lab)
