This 2×5 cm sensor’s internal components are protected by a unique Teflon™* screen that prevents dust and liquid from fouling the sensor, while still alowing water vapor to flow through. We recommend using our “beehive” radiation shield to protect the sensor from light, which can heat the sensor, skewing the air temperature and humidity readings. The VP-4 is a useful addition to a weather station to allow for evapotranspiration modeling and more.
