Springfield Vertical Thermometer and Hygrometer, Indoor Outdoor Thermometer, Wireless Humidity Meter for Patio, Garden, or Nursery areas (9.125-Inch)

Q: How does the humidity sensor work? I'm an owner and it seems to be controlled by a little spiral in the back.

The metal-paper coil hygrometer is very useful for giving a dial indication of humidity changes. It appears most often in very inexpensive devices, and its accuracy is limited, with variations of 10% or more. In these devices, water vapour is absorbed by a salt-impregnated paper strip attached to a metal coil, causing the coil to change shape. These changes (analogous to those in a bimetallic thermometer) cause an indication on a dial.

Q: How many inches is the glass thermometer itself? Thats the only part I need for replacement on a decorative unit. Thank you.

glass thermometer bulb&tube is 5" long total (3/4" red bulb is hidden behind the white plastic & 4 1/4" of glass tube is visible)

Q: What are the exact dimensions of this thermometer?

9 inches long, 3 inches wide, 1/2 inch high

Q: Does this have any sort of hangerr?

Yes, there is a little slot in the back to hang on a nail. Or, drill your own hole in the plastic housing for whatever hole you want.
