Spectrally Flat Class C pyranometer ISO9060
The pyranometers measure the global irradiance on a flat surface (W/m²); sum of direct solar irradiance and diffuse irradiance.
The PCTRA107...112 models falls within the Spectrally Flat Class C pyranometers according to the ISO 9060:2018 standard and meets the requirements of the WMO “Guide to Instruments and Methods of Observation”.
The internal temperature, relative humidity and pressure diagnostic sensors integrated allow keeping the pyranometer operating conditions under control all the time and foresee any maintenance work in advance, thus ensuring always reliable measurements.
The integrated bubble level and the adjustable feet facilitate horizontal positioning during installation. As option, the pyranometers can be equipped with a tilt sensor which, in addition to facilitating the installation of the pyranometer, allows continuous monitoring of the correct installation. The various models are distinguished by the type of output available and by the presence or absence of the "tilt" sensor.
The irradiance range for the analog output is user configurable (default, 0…2000 W/m²).
The pyranometers are factory calibrated in accordance with the ISO 9847:2023 (Type A1) standard: ”Calibration of pyranometers by comparison to a reference pyranometer”. The calibration is performed by comparison with the reference sample calibrated annually at WRC (World Radiation Center).
