William Grill wanted to make sure his freezer didnít cut out and ruin his frozen food. He was concerned that when he traveled, his food could defrost and re-freeze ó thus compromising his frozen steaks ó without his knowledge. So, he developed a gadget that measures freezer temperatures, keeps a history of variance and sends an alarm if freezer temperatures rise above a set range. The gadget is built around a small controller, an alarm and a temperature sensor. While temperature monitors are common, Grillís device remembers temperature variance and displays the length of time the freezer rises above the set temp. The gadget is relatively small and costs less than a couple of steaks bought on sale and stored in the freezer.
