The ThermaPen is a single purpose tool... to quickly and accurately determine the temperature of the substance or surface. It has a stated operating range between -50 and 572 ºF... well within the typical range encountered in most kitchens.
The ThermaPen is extremely simple to operate... add the battery, unhook the probe, and it turns on automatically. Place the metal probe on the surface or into a liquid and the temperature will be determined in a few seconds.
When we received the ThermaPen in the mail, we also received a signed and dated "Certificate of Calibration"... stating that it was accurate to 0.4 ºC. Nice!
We did our own random probing to see what the temperature of some of the items were around the RainyDay Kitchen... coffee (165ºF), tap water (63ºF), frozen ice pack (19ºF), boiling water (204ºF... we did take it off the stove).
Our non-scientific test gave us reasonable results so we are comfortable with taking the claims of the "certificate of calibration" at face value.
In the FirstUse review, we are going to make a Rosemary Lemon Roasted Chicken. We'll use the probe to check the various parts before and after the cooking process to ensure the proper degree of "throughness" without overcooking. Come back and check it out.
