This paper presents an experimental evaluation of different types of commercial chilled-mirror dew-point hygrometers designed to verify their metrological behavior. Specifically, an analysis of their measurement uncertainties and long-term stability is carried out. A computing method is applied to estimate the measurement uncertainty of an indirect determination of the relative humidity using a chilled-mirror dew-point hygrometer and a dry-bulb temperature sensor.
