Description

Maximum accuracy

The pyrheliometer accurately measures the direct solar radiation incident on the Earth’s surface. It is specially designed to meet the ISO 9060 standard and the guidelines established by the World Meteorological Organization (WMO).

Weatherproof design

The instrument is entirely made of corrosion resistant materials to ensure high resistance to weathering.

Multiple output options

It can be connected to any conventional datalogger to perform the data storage and its subsequent downloading and monitoring on a computer. It features a RS-485 serial port with MODBUS-RTU protocol or an analog output to choose between current or one of the three voltage ranges available.

Optional Schott filter

It suppresses all undesired wavelengths to allow measurements of the selected one only.

Multitude of applications

Its outstanding versatility makes it ideal for all kind of applications in many fields, the main ones being:

• Atmospheric research.
• Meteorology.
• Solar power plants.
