HD9906.51 – Ventilation and Heating Unit
Ventilation and heating unit for pyranometers, pyrgeometer and radiometers in fixed installations.
The heating and ventilation unit is meant to be used with solar radiation sensors (pyranometer, pyrgeometer and radiometer) and can be used outdoor under any weather conditions.
The ventilation of the instruments increases the precision of the measures by making the pyranometer’s temperature uniform, in particular it avoids the deposit of dew and frost on the optical parts of the sensors and reduces the off-set of type A (present in pyranometers and pyrgeometers) caused by the cooling of the dome with respect to the instrument’s body.
The HD9906.51 unit can be used with LPPYRA02 and LPPYRA10, with the pyrgeometer LPPIRG01 and the radiometers LPPHOT02, LPUVA02 and LPUVB02.
