Onset HOBO U12-015 Stainless Steel Temperature Data Logger

The HOBO U12-015 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 U12-015 Stainless Temperature Data Logger withstands process conditions from pasteurization to flash freezing and washdown. The U12-015 Stainless is also ideal for high-temperature or deep underwater applications.
