Using VU01 is easy. The footprint of VU01 is small, which prevents accumulation of snow. The ventilator power is relatively high in order to increase the airflow. VU01 may be used in combination with Hukseflux’ SR20 secondary standard pyranometers and IR20 and IR20WS research grade pyrgeometers. This unit provides an airflow over the instrument body and dome and has a 5 W and a 10 W heater on board to heat the air. The ventilator is generally used continuously, the heater is typically controlled by the datalogger. Ventilation is typically used with high accuracy measurement requirements. In such cases the need for a high level of instrument maintenance and dome cleaning still exists, evaporating droplets of water might leave stains on the instrument domes. The bottom of VU01 provides access to the removable dust filter.
