The full measurement range is -40 to 212°F (-40 to 100°C). A selectable measurement-averaging feature further improves accuracy. Reliable service is assured by a stainless steel sensor tip and robust cable rated for immersion in water up to 50°C for up to 1 year. They come available in 2m, 6m and 17m lengths.
