[3 in 1 Barometer Thermometer Hygrometer] Outdoor barometer, hygrometer, and thermometer accurately measures humidity, air pressure, and temperature with a range of 95.6 to 103.8 kPa (28.2 to 30.8 inchHg), -40 to 140°F (-40 to 60°C), and 0 to 100% RH. The barometer helps indicate weather changes by measuring atmospheric pressure trends. [High-Quality Material] This barometer is constructed from premium steel for durability and long-lasting performance. The 3-in-1 instrument features an 8-inch dial with clear markings for easy reading from a distance. A hanging hole on the back allows for convenient wall mounting. [Dial Type Barometer] The primary function of this barometer is to monitor barometric pressure trends. You can use the adjustable pointer to mark current pressure readings for future comparison and weather prediction. [Indoor or Outdoor Use] This weather station can be placed indoors or outdoors.
