Acu-Rite 795 User Manual

When temperature rises, the liquid inside the glass thermometer becomes less dense 

and the liquid-filled bulbs will sink. When the temperature drops, the liquid inside the 

thermometer becomes more dense and the liquid-filled bulbs will float.

A. The temperature is determined by the lowest floating bulb in 

the thermometer. 

B. When there is a bulb in the middle, the temperature is between 

that degree and the lowest floating bulb. 

C. If all the bulbs float to the top, the temperature is under the 

lowest floating bulb. 

D. If all the bulbs sink, the temperature is over the highest bulb.

Variations in barometric pressure are associated with changes 

in the weather. The Storm Glass barometer accurately forecasts 

changes in the weather hours in advance because the water level in the spout of the 

Storm Glass reacts to changes in the atmospheric pressure. 
A low water level in the spout indicates HIGH pressure, and fair weather can be 

expected. A high water level in the spout indicates LOW pressure, and precipitation can 

be expected. In cases of severe weather or major storms the water may even run out of 

the spout.
The Storm Glass does not indicate exact pressure, like a numeric barometer, but it is 

accurate enough to display the change in air pressure between the basement and attic 

in the same house.
