Question: Can this be used for frying and candy-making?  The temp range seems to suggest  yes, but I'd like to know if that's specifically stated anywhere.
Document: This is my second polder thermometer - and even better than the first one I owned - which died after ten years or so. A faster reading, narrower point and larger display are the improvements over the first model. I got this just before the holidays and used it for everything from toffee to prime rib - all successes. If you are cooking an expensive roast or something it is so worth it to have this handy little tool with a giant temp. range!
I found this to be exactly what I needed. I can push the button to turn it on, stick it in and forget. It beeps when the reading stabilizes and then I can pull it out and wash off the probe. It's a great unit for what I consider to be a fair price. Meets my needs and I'd buy it again for the same price.
When it was delivered, the battery cover does not close properly, but I somehow managed to make the cover stay. But if falls off again, it is another round of fighting it with your fingers.This morning, this thing started making loud beeping noise from the Kitchen and woke me up. Only to stop the noise is the remove the batteries.It makes no sense a thermometer has a Beeper!!!! !
Only used it once  on Thanksgiving turkey. It worked well. Easy to read and accurate! Turkey was cooked before the sensor on the bird popped up.
Answer: I bought it for someone else.  He tells me that it works very well for checking the temperature of hamburgers, chicken breasts and other items on his grill.  I do not think it states "frying and candy-making" anywhere.  My English cookbook says that toffee is boiled until it gets to 270 F., and fudge at 240 F.  So that should be OK for the candy-making.  I am not sure how far into the liquid one can put the probe.  It is very fine and ideal for hamburgers, etc.
