Step 1
Decide on the purpose. All barometers are used to measure changes in atmospheric pressure but their secondary purpose may be quite different. High tech digital barometers can be used to measure and record extremely accurate weather changes for the aspiring scientist. Decorative antique models will often appreciate in value, making them a good choice for collectors.

Step 2
Realize that many modern barometers are excellent examples of technological advancement. They can include thermometers, clocks and measuring devices for humidity and dew point. If you purchase a multifunctional barometer, this may cut down on the cost of other weather measuring equipment and will also be a more efficient and space saving device.

Step 3
Choose your style. Barometers come in a whole range of different shapes and sizes. Pick a model that suits your needs. Pay special attention to the materials and craftsmanship as some models can be extremely fragile and intricate. If you are using the barometer more for decor, choose one that compliments other items in your home.

Step 4
Look around. Many websites sell different types of barometers. These can vary wildly in quality and price. Check out a few different ones before deciding to buy, to make sure you find a good deal.
-
Step 5
Check the guarantee. Like purchasing anything, it is wise to check return policies before buying. Good quality merchandise will normally come with a guarantee to either replace or repair the barometer in case of malfunction. If buying online (see Resources below) ensure that insurance is included with shipping or buy additional protection to guard against breakages.
