Overview

Optical Interface for 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
