Calibration

Field instruments can be calibrated in place using portable reference standards or sent to a laboratory for a more thorough calibration if needed. Vaisala provides a variety of instruments for the calibration of temperature, relative humidity, dewpoint, and carbon dioxide instruments. Vaisala also operates accredited calibration laboratories in Finland, Japan, and the USA.
