Kalibrointiopas

T​ässä oppaassa on perustiedot kalibroinnista. Oppaassa käsitellään kalibroinnin perusperiaatteita ja kalibroinnin tarpeeseen vaikuttavia tekijöitä. Oppaassa on lisäksi yksityiskohtaisia tietoja suhteellisen kosteuden, kastepisteen lämpötilan, lämpötilan ja ilmanpaineen kalibroinnista.
