CHP1-L Pyrheliometer
Services Available

Overview

The CHP1-L, manufactured by Kipp & Zonen, is a pyrheliometer used for unattended direct solar-radiation measurement. It is designed specifically to measure the direct beam solar irradiance with a field of view limited to 5 degrees. This is achieved by the shape of the collimation tube, precision apertures, and the detector design.

Detailed Description

To monitor direct normal irradiance, a CHP1 Pyrheliometer is mounted to a user-supplied sun tracker such as Kipp & Zonen's Solys2. The CHP1 pyrheliometer measures the direct-beam solar irradiance with a field of view limited to 5 degrees. The limited field of view requires the CHP1 to be continuously pointed toward the sun. The Solys2 Sun Tracker rotates on two axes and uses a GPS receiver to keep the CHP1 aimed at the sun throughout the day.
