Test and Measurement Equipment
Albedometers
Albedometer basically consist of two pyranometers, mounted
back-to-back, one looking upward (sky)
and one downward (earth).
The upward pyranometer measures the the incident global radiation (direct radiation + diffuse
radiation) striking the ground, while the downward one, measures the global radiation reflected from the ground.
The outputs of the two pyranometers electric signals (the two pyranometers are
coupled in
order to have the same sensitivity) can be directly sent to a data logger or to an automatic data processor.
Pyranometer First Class
Pyranometer is a type of instrument used to measure broadband solar irradiance on a planar surface
and
is a sensor that is designed to measure the solar radiation flux density (in watts per meter square)
from a field of view of 180 degrees.
First Class Pyranometers fully comply with ISO 9060 standards, and meet the requirements defined by the
World Meteorological Organization (WMO).
Pyranometer Second Class
Second Class Pyranometers fully comply with ISO 9060 standards, and meet the requirements defined by the
World Meteorological Organization (WMO). Every pyranometer is calibrated separately and is supplied
standard with a WRR (World Radiometric Reference) Report of Calibration.
NET Irradiance Meter
NET radiometer is designed to measure the Net radiation passing through a surface, across the spectral
range between the near ultraviolet and the far infrared. The Net radiation is defined as the difference between
the radiation that strikes the top surface, and the radiation that
strikes the bottom surface of the net radiometer.
