Radiation Shields protect sensors from the effects of sunlight and rain to ensure high accuracy air temperature measurements.
The RS3-B Solar Radiation Shield is the smallest and most economical shield and works with most of Onset's external temperature and Temp/RH sensors, including those for the U23, MX2300, USB Micro Station, U30 and RX3000 Weather Station products. (Note: the RS3-B is a direct replacement for the RS3 and includes a wider fitting for the MX2300 loggers)
The RS1 Solar Radiation Shield is suited for all Onset's outdoor temperature dataloggers, with a larger capacity. It is suitable for the U23 and MX2300 dataloggers when used with the appropriate bracket.
The M-RSA Solar Radiation Shield is the same as the RS1 but comes pre-assembled.
