The Middleton Solar DN5-B is an upgraded version of the DN5. It is an affordable precision pyrheliometer for measuring solar Direct Normal Irradiance (DNI) when aimed at the sun. It exceeds the international accepted specifications for a Spectrally Flat Class B pyrheliometer. The DN5-B has a passive microvolt output. The DN5-BE version has an in-built amplifier to give a millivolt output for easy signal measurement.

EXCELLENT PERFORMANCE, USER FRIENDLY, DURABLE
Window is optical sapphire for broad bandwidth and superior chemical & scratch resistance compared to glass or quartz.
Flush-mount window to prevent obstruction by rain or debris.
Marine-grade anodised aluminium for corrosion resistance.
Compact size and light weight.
Use the AST-02 Active Solar Tracker to aim the DN5-B at the sun.
