Kalibrierbuch
Das Vaisala Kalibrierbuch dient der allgemeinen Einführung in die Kalibrierung. Es behandelt die Grundprinzipien sowie die Faktoren, die eine Kalibrierung erforderlich machen. Das Buch enthält auch spezifische Informationen zur Kalibrierung der relativen Feuchte, der Temperatur, der Taupunkttemperatur und des barometrischen Luftdrucks. Das Buch ist nur in englischer Sprache verfügbar.
