Pyrheliometers
The pyrheliometer is designed for unattended normal incidence direct solar radiation measurement research.
A pyrheliometer is an instrument designed specifically to measure the direct beam solar irradiance with a field of view limited to 5 °. This is achieved by the shape of the collimation tube, with precision apertures, and the detector design.
The front aperture is fitted with a quartz window to protect the instrument and to act as a filter that passes solar radiation between 200 nm and 4000 nm in wavelength. CHP 1 includes a rain shield and integrated alignment aids.
CHP 1
The CHP 1 pyrheliometer is the latest development in the field of solar radiation measurement. Building forth on the legacy of the CH 1, this instrument offers further improved accuracy and reliability.
