The innovative SPN1 Sunshine Pyranometer measures global (total) and diffuse radiation, and sunshine state – all in one instrument.

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

The SPN1 is exceptionally easy to use; it needs no routine adjustment or polar alignment and works at any latitude. It is an affordable and effective alternative to shade-ring pyranometers, pyrheliometers and traditional sunshine recorders.

Output from an SPN1 Sunshine Pyranometer enables calculation of DNI (Direct-Normal Irradiance) in sun tracking, horizontal and tilted installations.

An internal heater keeps the dome clear of dew, ice and snow down to -20°C (in still air conditions), ensuring reliable readings in difficult climatic conditions.

The SPN1 is protected by patents EP 1012633 and US 6417500.
