Product Description

The SPN1 Sunshine Pyranometer from Delta-T Devices is a solar radiation measurement instrument that provides 2 analogue voltage outputs for global and diffuse radiation, as well as a digital output for sunshine duration.

It is a great alternative to shade-ring pyranometers and needs no routine adjustment or polar alignment and works at any latitude.

Fully compatible with our data loggers.
