The Nautilus Series consists of two full-featured, single-channel temperature loggers designed for "wet" environments at varying temperature ranges - from oceans, streams, and wastewater to food and other liquids, Ideal for rugged applictions, Nautilus loggers come in stainless steel or aluminum and offer a high temperature option for environments where conventional loggers are unable to survive.

The Nautilus 85 is a durable, robust data logger that can monitor temperature in a variety of applications and is particularly well suited for the food and beverage, biomedical, pharmaceutical industries. As well as industries with hostile or "wet" environments (i.e. wastewater treatment plant). Housed in a stainless steel or aluminum casing, it can withstand virtually any environment and with an operating pressure range up to 2000 PSI, it is ideal for monitoring temperature in any type of water including oceans, ponds, rivers, streams and wastewater.

The high temperature capabilities of the Nautilus 135 make it the ideal logger for monitoring temperature in extreme environments or environments where conventional data loggers are not able to survive.
