I'm supposed to make a large sum of chocolates for a party, but my thermocouple thermometer has started measuring thirty degrees low. I don't have time for anything to arrive in the mail, and I need to temper some chocolate. Can anyone make a suggestion?

Where are you located (i.e. nearest city or town), and what's your budget?

Given the temperature range involved, a basal thermometer should do the trick, and according to eG member Robert Jueneman, they're reasonably priced and accurate, and they seem to be widely available (e.g Eckerd, Rite Aid, Target).

Smart & Final has regular old school mercury and newer instant read thermometers near the checkout. They are a fairly large chain, located in most larger cities.

Go to your drugstore, find a regular thermomter, the kind your Mom used to put under your tongue when you had a fever.

Look, the melting temp and working temp of couverture is almost the same as human body temp (32 C vs 36/37 C). The "fever" thermometer is accuate within 10ths of a degree.

It'll do, it'll do very well, and it's cheap and easily obtainable.

I'm in Madison, WI.

That said, I think one of the above options will cover it - you folks are absolutely 100% full of win. Thanks!

The standard oral thermometers at Wallgreens dont' go above 102F or below 95F; the ovulation thermometers appear to have an even narrower range. Any suggestions for a specific model?

Hm. That range seems too high (based on what pastrygirl, who's a pro, said in another topic). If there aren't any decent kitchen supply shops in your area, what about lab supply shops?

30 seconds of googling came up with a couple of kitchen supply stores in Madison, including a WIlliams Sonoma. Seems pretty easy to call one of them up.

I called both of the restaurant supply stores Google returned; Williams Sonoma had a thermocouple thermometer, but for more than I'd just paid for 22 pounds of coverture. Ouch.

It turns out that my $100+ thermometer is working fine - it's the probe that's malfunctioning. In what I feel was a fairly heroic fix, I removed the thermocouple from the original probe and, after hollowing it out with a tiny screwdriver, inserted a replacement thermocouple. It measures beautifully, though the poor thermal conductivity makes it awfully slow.

I pick up infrared thermometers from Canadian Tire when they go on special - I find they work quite well for tempering. A bunch of folks from the chocolate conference last year took them home.

Can you link to the specific model? My present IR thermometer is inadequately accurate, and I would be interested in an inexpensive replacement of required precision.

Here you go. Now ignore the $99 - they are generally on sale. Anything from $39 up.
