    Validating the pyroelectric radiometer
    (Tartu Ülikool, 2021) Duong, Thi Kim Ngan; Ansko, Ilmar; Tartu Ülikool. Loodus- ja täppisteaduste valdkond
    This master’s thesis describes the in-lab validation of the electrically calibrated pyroelectric radiometer (ECPR). The ECPR was inter-compared with two reflection-type trap detectors, a FEL lamp, and an absolute electrical substitution pyrheliometer. All the instruments have valid calibration certificates. The measurement methods, uncertainty analysis, and results are presented. The ���� numbers in all cases were satisfying.
