Digital Hygrometers: Indoor and Outdoor Thermo-Hygrometers
Digital thermo-hygrometers show temperature and relative humidity together. Built-in sensor models measure the room they sit in, external sensor models read a second location through a probe cable, and dual temperature models show indoor and outdoor readings side by side.
