Overview

Optical Interface for Water Temp. Pro data transfer

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 (either the assembly-required RS1 Solar Radiation Shield or the pre-assembled M-RSA Solar Radiation Shield).

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: The plastic case will become brittle at temperatures lower than -20°C. If the logger is deployed in a location where the temperature drops below -20°C, make sure the logger remains stationary and is not pulled on or struck. Return the logger to above -20°C before handling.
