[. . . ] Both the PTU307 and HMT337 avoid this problem by warming the probe. When warmed, the relative humidity inside the probe stays below the ambient level. With an accurate temperature measurement, the ambient dewpoint can be calculated precisely. To obtain the ambient relative humidity, an additional probe measures the ambient temperature, 20 Open shield prevents microclimates The warmed humidity probe of the HMT337 / PTU307 is mounted in a shield which is open at the bottom to ensure steady air circulation to the sensor even in calm weather. In traditional radiation shields sleet For calibration, a portable HMP77 reference probe is easy to attach beside the HMT337 or PTU307 probe. Vaisala Instruments Catalog 2009 Ref.
