Delta OHM Pyranometer

Every pyranometer composing the albedometer is calibrated separately as per the WRR (World Radiometric Reference) standard and is supplied with the relevant Report of Calibration.

These are strong and reliable ground-based instruments, especially designed to be used under all weather conditions. They are suitable for installation of the field.

Recommended use: climatological research, weather stations, road weather stations, agriculture stations, etc. 

WIRING DIAGRAM LPPYRA11, LPPYRA05 - LPPYRA06

Delta OHM manufactures three different models of albedometers: - LPPYRA11 is constructed starting from two Secondary Standard Pyranometers - LPPYRA05 is constructed starting from two First Class Pyranometers - LPPYRA06 is costructing starting from two Second Class Pyranometers All pyranometers are according to ISO 9060 standards and to specifications published by the World Meteorological Organization). An albedometer basically consists of two pyranometers, mounted backto-back, one looking upward (sky) and one downward (earth). The upward pyranometer measures 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 can be directly sent to a data logger or to an automatic data processor. The two pyranometers which made up the LPPYRA05 and LPPYRA11 are coupled in order to have the same sensitivity. Albedo is the fraction of solar radiation that is reflected from the ground, with respect to incident radiation:
