Get highly accurate water temperature readings with the HOBO Pro v2

A durable water temperature data logger with 12-bit resolution. Complete with a precision sensor for ±0.2°C accuracy, this logger measures temperatures between -40°C and 70°C (-40°F to 158°F) in air and up to 50°C (122°F) in water. The waterproof, streamlined case allows for extended deployment in freshwater or saltwater. And the optical USB interface lets you offload data even while the logger is wet or under water. A solar radiation shield is required to obtain accurate air temperature measurements in sunlight (RS1 Solar Radiation Shield, assembly required; M-RSA pre-assembled Solar Radiation Shield).

The HOBO Water Temp Pro v2 logger is designed with a durable, streamlined, UV-stable case for extended deployments measuring temperature in fresh or salt water. The small size of the logger allows it to be easily mounted and/or hidden in the field. It is waterproof up to 120 m (400 feet) and rugged enough to withstand years of use, even in stream conditions. It has enough memory to record over 42,000 12-bit temperature measurements.

The logger uses an optical USB communications interface for launching and reading out the logger. The optical interface allows the logger to be offloaded without compromising the integrity of the seals. The USB compatibility allows for easy setup and fast downloads.

Features

Research-grade measurements at an affordable price
Waterproof to 120 meters (400 feet)
Data readout in less than 30 seconds via fast Optic USB interface
Compatible with HOBOware and HOBOware Pro software for logger setup, graphing, and analysis

Important Information

Requires HOBOware software and either a U-DTW-1 Waterproof Shuttle or the Base-U-4 Optic USB Base Station for configuration and data offload. Please see related items below.
