Overview

Use the RS3-B Solar Radiation Shield with HOBO external sensors for improved temperature measurement accuracy in locations exposed to sunlight. The small size and unobstructed airflow of this shield provides a faster response to changing conditions than larger radiation shields.

The RS3-B Solar Radiation Shield works with most of Onset’s external temperature and temperature/relative humidity sensors, including those for our award-winning HOBO Weather Station products.

For customers looking for a radiation shield large enough to mount a HOBO data logger inside it, Onset also offers two other models of solar radiation shields; the RS1 and the pre-assembled M-RSA

The country of origin for this product is the United States. To see the full specifications for this product, please see our product manual found under the documentation tab if available
