PRODUCT SPECIFICATIONS
FEATURES
• Monitor temperature
in water, food or other
liquids
• Available in stainless
steel or aluminum

The Nautilus85 and 135 are durable, robust data loggers that can monitor temperature in a variety of appli-
cations, but they are particularly well suited for the food and beverage, biomedical, pharmaceutical, and
industries with hostile or "wet" environments (i.e. wastewater treatment plant). Housed in a stainless steel
or aluminum casing, they can withstand virtually any environment and with an operating pressure range
up to 2000 PSI, they are ideal for monitoring temperature in any type of water including oceans, ponds, rivers,
streams and wastewater.
