Overview

The CHP1-L, manufactured by Kipp & Zonen and cabled by Campbell Scientific, is a pyrheliometer used for unattended direct solar-radiation measurements. 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.

Key Advantages

For Unattended Direct Solar-Radiation Measurements

Technical 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.

Benefits

  • ISO First Class
  • Built-in temperature sensors
