The specific reading isn’t all that important in this regard; what matters most is in which direction the needle moves over the course of hours or days.

Can a barometer be fixed?
Aneroid barometers are often broken by mishandling or corrosion and can be restored to life. If the front glass is damaged we can make new beveled glass parts and install the pointer hands. The mechanisms can be repaired and new vacuum capsules installed if necessary. Again, polishing is available.
What does it mean when a barometer doesn't move?
Your main concern in reading a barometer is whether the pressure is rising or falling. If the needle does not move it would mean that the barometer is "holding steady" and similar weather conditions should continue.

How do I know if my barometer is broken?
Hold the instrument at the 45-degree angle and check the the level of the mercury in the glass tube with a long "stick" barometer. If the barometer is working correctly, the mercury inside will rise quickly to fill the very tip of the tube, leaving no air bubble.
How do you clean a barometer tube?
Holding the syringe connector, gently pull the plastic covered wire back out of the fine tube. If you pull too quickly, the fine tube will bunch up and be damaged. Charge the syringe with a 7:1 water : Medmaw cleaner mixture and attach the connector. Fill the barometer tube, leaving the fine tubing in place.

Air from the outside is going to constantly diffuse into your home, maintaining it at the same pressure as the surroundings. Hence your barometer can get a reading because the pressure will be the same indoors as outdoors at the same altitude.
How do you fill a glass barometer?
This device can be filled using a combination of hot and cold water, and is best to fill on a good day when the local pressure reads 30 and above. Submerse the barometer completely in the hot water until bubbles stop coming out of the spout. Place a finger over the spout and move the barometer to the cold water.

What is the first barometer?
Mercury: The mercury barometer, sometimes called a stick barometer, was the first to be invented. It uses an open tube system with a pool of mercury that rises and falls with pressure changes. They only work at an altitude up to 1,000 feet. Aneroid: The aneroid barometer doesn't use any liquids.
How long does it take for a barometer to measure air pressure?
A barometer measures air pressure and can forecast the weather within a 12 to 24 hour period. Air pressure can be measured in inches of mercury, millimeters of mercury, or hectopascals, depending on where you live and the gauge on the instrument.
How to read barometer pressure?
1. Set the manual hand to the current reading. Turn the barometer's center knob so that the arrow rests directly above the indicator arrow (this is the current barometric pressure for your location). You can identify the set hand by its notched arrow about halfway down the hand.
What is an electronic barometer?
Electronic: Electronic barometers are a little more complicated to understand, but they employ sensors and strain gauges that cause changes in voltage that can be converted to a display of pressure for the user.
Which way should the indicator hand rotate on an aneroid barometer?
If you have an aneroid barometer, the indicator hand should rotate clockwise around the dial.
What is the adjusting screw on an aneroid barometer?
Aneroid barometers use an “adjusting” screw on the back of the barometer to calibrate this needle to local pressure readings. Check the manual or diagram that came with your barometer to confirm the location of the adjusting screw.
What is an aneroid barometer?
Aneroid (nonliquid) barometers use incremental fluctuations in pressure upon the metal of a sealed evacuated (air free) drum or capsule to measure air pressure change. A faceplate and needle—similar to a clock face with hands—translates these changes mechanically into a readable measurement as the needle moves around the “face” of the barometer.
