MV-01 Ventilator & Heater

The MS-80 pyranometer in combination with the MV-01 ventilator unit will keep the pyranometer dome free of dew, ice and snow.

The MV-01 benefits from a low power fan and effective heater, which can be separately switched on/off during the variable operating conditions. Due to the vertical design of the pyranometer sunscreen the air outlet will remain free from snow and ice. The ventilator unit is protected against overheating through a temperature safety switch.

The ventilator ensures the data availability of the MS-80 under all environmental conditions.
