I have two digital cooking thermometers, a ThermPro and a Lavatools Javelin Pro.
The ThermPro is the kind with a probe inserted into the meat while it cooks.
Javelin Pro is an instant read with the jackknife type probe that flips out.

Today I was cooking a boneless pork roast and had theThermPro inserted and set
to go off at 145 degrees. It did. When I went to take the roast out of the oven,
I decided to check it with the Javelin Pro, only because it's new and I hadn't
used it yet. The Javelin Pro read 138 degrees. A 7 degree difference? Really?
Which one was right? Do I take the roast out or leave it for a little while
longer. Both got high ratings where I bought them. And the Javelin Pro is a $50
thermometer. Where do I place my trust?

Have you checked them in water together? I've had differences on the
same thermometer when the probe was inserted just a little distance
away. Check in ice water and hot water and get back to us.

Exactly. Calibrate to a known standard. First thing I do for Christmas Candy season is I boil the thermometers! 212F/100C!
