EQ09.. Solar Total Pyranometers
- SKU: Middleton Solar-EQ09
Description
The Middleton EQ09-A is a precision Pyranometer for measuring solar Global Horizontal Irradiance
(GHI). It exceeds the International Organization for Standardization (ISO) specifications for a
Spectrally Flat Pyranometer of Class A. Class A is the highest accuracy Class. The EQ09-A
incorporates a unique thermoelectric sensor that has exceptionally low directional error without
compromise to signal strength or response time. The EQ09-AE version has an in-built amplifier to give
a millivolt output for easy signal measurement.
