The Vaisala Solar Radiation Shield Plus Mount DTR502B is a professional-grade, naturally ventilated meteorological shield designed to protect precision probes from external thermal interference and precipitation. Engineered with highly reflective white outer plates and heat-absorbing black inner surfaces, it blocks both direct and scattered solar radiation to ensure highly accurate, unbiased ambient air temperature and humidity readings. This durable, maintenance-free polymer shield is purpose-built to house the probe heads of Vaisala's premium instruments—such as the HMP3, HMP7, and HMT330 series—and features a versatile, integrated mounting kit that allows for secure installation on vertical poles, horizontal beams, or flat outdoor walls.
