Class A Pyranometers

Radiometer for solar irradiance measurement, according to ISO 9060 and WMO No. 8 (Part I, Chapter 7) standards. These sensors are classified as ISO 9060 Class A. With a total daily uncertainty of only 2% within 0...180° field of view, fast response time, these sensors are ideal for users requiring high-end accuracy and reliability. Calibration traceability to WRR. DPA953.1 features different measurements in the same sensor as: irradiance in W/m², instrument body temperature, tilt angle, internal humidity, internal pressure and ventilator speed (DPA953.1).
