The HOBO U12 Stainless Temperature Data Logger is ideal for food, pharmaceutical, autoclave, and other applications where high-accuracy temperature data is critical. With its broad temperature range (-40 to 125C) and food-grade stainless steel housing, the U12 Stainless Temperature Data Logger withstands process conditions from pasteurization to flash freezing and washdown. The U12 Stainless is also ideal for high-temperature or deep underwater applications.
