Precision ground glass dome
Collect high-quality global and diffuse radiation as well as sunshine duration using the Delta-T SPN1 Sunshine Pyranometer. The SPN1 Pyranometer is a precision solar radiation measurement instrument with a ground glass dome and is designed for long-term outdoor exposure. It is an effective alternative to shade-ring pyranometers, pyrheliometers, and traditional sunshine recorders.
The SPN1 Pyranometer is exceptionally easy to use; it needs no routine adjustment or polar alignment and works at any latitude. 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.
The SPN1 Pyranometer is ideally suited to multiple solar radiation measurement application areas, including PV (photovoltaic) efficiency monitoring, air pollution studies, cloud cover research, ET and heat flux studies, canopy analysis, and building energy management systems.
