Instant-Read Thermometer

Our favorite instant-read thermometer has been upgraded with a model that won’t turn off, even when wet. The screen remained lit when we checked the temperatures of ice water, chicken breasts, and roast beef. The ultimate challenge came when it was time to clean: We ran the thermometer underneath hot water—and the LCD screen stayed on. This new model contains Biomaster, a thermally stable antimicrobial additive that the company claims prevents the growth of bacteria.
