This probe can withstand up to 450C or 840 F high temperature in sustained period.
But is not waterproof.
It is good for high temperature grilling to monitor temp. of pit.
Price is $10, and air mail cost is $10, total $20.
For all old customers, I will offer ONE free of probe.
You need only to pay shipping cost of $10.
If you post serious reviews with pictures of my controller & thermometer on BBQ forums (not here), I can even waive the shipping cost.
