SPN1 - Sunshine Pyranometer

Measures solar radiation and sunshine duration Global (Total) and Diffuse irradiance in W.m-2 DNI (Direct-Normal Irradiance) calculation WMO sunshine threshold: 120 W.m-2 direct beam No moving parts, shade rings or motorised tracking No routine adjustment or polar alignment Works at any latitude Precision ground glass dome Solar Radiation Sensor Shadow Mask The SPN1 Sunshine Pyranometer is a meteorological class solar radiation measurement instrument with a built-in heater, and is designed for long-term outdoor exposure. It is an affordable and effective alternative to shade-ring pyranometers, pyrheliometers and traditional sunshine recorders. The SPN1 Sunshine Pyranometer is exceptionally easy to use; it needs no routine adjustment or polar alignment and works at any latitude. The SPN1 Sunshine Pyranometer is protected by patents EP 1012633 and US 6417500. An internal heater keeps the pyranometer dome clear of dew, ice and snow down to -20°C (in still air conditions), ensuring reliable readings in difficult climatic conditions.
