Heating and ventilation unit for RSG2std

The heating and ventilation unit RSG-VU is meant to be used with NESA Secondary standard solar radiation sensors and can be used outdoor under any weather conditions. Makes the solar radiation sensor compliant with IEC 61724-1.

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 caused by the cooling of the dome compared to the instrument’s body.

It’s possible to use the heating under extreme environmental conditions to prevent ice formation on the dome of the pyranometer (when the heating is on, you should consider that the off-set may increase, therefore we suggest the use of the heating only for the time necessary to remove snow or ice formed on the instrument’s surface).
