Yes. A correct sensors calibration is mandatory to ensure reliability, accuracy and precision.
Our laboratory is equipped with three digital SUNMETER solarimeters (called primary SUNMETERS).
Our laboratory is equipped with three digital SUNMETER solarimeters (called primary SUNMETERS), calibrated with the primary Reference Cell referenced by Fraunhofer Insitute (DE) .
For Thermopile Pyranometers , our primary Pyranometer is a Secondary Standard SR20. The SR20 output values are read by a Keysight (HP), a 6+1/2 digit multimeter.
The calibration process implies direct sunlight exposure.
After being assembled, every solarimeter is calibrated with a primary SUNMETER by setting the amplification coefficients necessary to equal the correct irradiation value.
