INTRODUCTION
The pyrheliometer LPPYRHE16 measure the direct solar irradiance (W/m
2
).
The receiving surface must be positioned perpendicularly to sun’s rays, via a solar
tracker or else.
LPPYRHE16 is a B class pyrheliometer in accordance with ISO 9060:2018 standard
and with the criteria of the WMO “Guide to Meteorological Instruments and Methods of
Observation’”, seventh edition (2008).
The pyrheliometer has a field of view of 5°, in accordance with ISO 9060:2018 stand-
ard and WMO guide.
The pyrheliometer is available in the following versions:
•
