Acu-Rite 795 User Manual

1) Fill a container with water — use distilled water to help prevent streaks on the glass.
2) Add food coloring to the water to make it easier to see.
3) Push the injection tube onto the syringe (shown below).

4) Fill the syringe with the colored water.
5) Insert the injection tube into the spout of the Storm Glass. The tube should go 

completely down the spout and stop at the top of the glass chamber. DO NOT 

INJECT THE COLORED WATER AT THIS TIME.

6) Hold the Storm Glass with one hand while holding the syringe with the other. Turn 

the Storm Glass upside down.

7) Slowly inject the colored water into the Storm Glass until it is about half full (shown 

below). 

8) Remove the injection tube from the Storm Glass. 
9) Turn the Storm Glass back to its upright position and set it on a flat surface.

The water should be about 1” up the spout of the Storm Glass. If the water is not at this 

level, fill the syringe with air and insert the filling tube back into the top of the water 

chamber. Do not turn the Storm Glass upside down for this procedure. Inject air into the 

chamber.
Water will rise up the spout and may overflow. You may want to do this over a sink 

and have a cloth or paper towels handy for clean up. Once you remove the injection 

tube the water should be further up the spout. Once filled, the water in the spout will 

immediately respond to changes in barometric pressure. Some evaporation may occur 

over time and additional water can be added as needed.
