The Middleton Solar DN5 is an affordable precision pyrheliometer for measuring the solar direct radiation when aimed at the sun. It exceeds the international accepted specifications for a First Class pyrheliometer. The DN5 has a passive microvolt output, and the DN5-E 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 APT-01 Automatic Passive Solar Tracker to aim the DN5 at the sun.
