Re: Temperature Indicator Crayons
Sandie
Temperature indicator crayons change color at a specific temperature and are
quite reliable. For example, one may go from yellow to red/brown and 550 degrees
F. They don't tell what the temp is, only that you've reached or exceeded the
set temperature. They're a cheap backup. Find at Eurocom -- 4 bucks each ..
