Vaisala DTR502B Radiation Shield with Mounting Kit or HMP3 HMP7 HMP9 HMT333 HMT337 PTU303 and PTU307

The maintenance-free DTR502B shields protect the humidity and temperature sensors from solar radiation and precipitation. They provide excellent ventilation while blocking both direct and reflected solar radiation.

The special plastic used in the plates has excellent thermal characteristics, the white outer surface reflects radiation, the black inside absorbs accumulated heat. The shields can be easily installed on either a vertical pole, horizontal beam, or a flat surface.

The DTR502B radiation shield can be used with the HMP3, HMP7, HMP9, HMT333, HMT337, PTU303 and PTU307. For HMP9, an additional sensor head support (item code 215130) is needed.
