The AL-130 Albedometer Bracket is designed to accommodate the SP-510 upward-looking thermopile pyranometer and the SP-610 downward-looking pyranometer to create an albedometer. It can also be used to mount other upward and downward facing sensors, such as our pyrgeometers. The AL-130 bracket is designed to be mounted to a mast or pipe with a 1.3 to 2.1 outer diameter and has an integrated bubble level to make leveling simple and accurate for proper sensor installation.
