Overview
An ideal data logger 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, this logger withstands process conditions, from pasteurization to flash freezing and washdown. This logger is also well suited for high-temperature or deep underwater applications.
