U12-015

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

• Food-grade 316L stainless Temperature loggers
• High-accuracy, extended temperature range
• Suitable for high pressure applications to 2200psi
• Fast readout via direct USB interface
