Product Description

The DR01 is a high-accuracy direct (normal incidence) solar radiation sensor, also known as a pyrheliometer. This pyrheliometer is featured with a heated window to increase data availability and is used in two-axis tracker-mounted operation for both solar resource assessment as well as solar monitoring (for concentrated solar energy).

The DR01 complies with the first class specifications of the ISO 9060 standard and the WMO Guide.
