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.

Time response: 2.5 times faster than the RS1 and M-RSA
