The Best Barometer
If you are an outdoor enthusiast then you must know how important it is to keep up with changing weather patterns throughout the day. One of the key factors outdoor enthusiasts especially hikers and anglers consider is atmospheric pressure and altitude however, most recently barometers have been replaced by technological advancements such as phones and fitness watches.
Outdoor enthusiasts however, acknowledge and appreciate the authenticity of barometers and as such, still use them. Barometers have also been revolutionized and their make has improved over time. Listed below are 10 best barometers in 2020; outlining their best qualities and are more likely to change your perception to why it is a great idea to have them.
How To Choose A Barometer – Buying Guide
How often will you need to check your barometer? If you are unlikely to check it more than a few times a day, then a standard model from a reputable manufacturer will probably be all that you need. A good quality instrument will be able to demonstrate significant pressure changes.
When choosing a barometer to purchase, physical examination also helps. If the seal on the capsule fails, the barometer is terminally dead. And if the capsule is not perfectly uniform in thickness, the readings may not be reliable. Capsules are not difficult to make, and most are reliable, but their quality is closely related to the price and the length of the guarantee. Good barometers should come with a lifetime guarantee, or close.
Allowing For Altitude
Altitude should always be considered when choosing a barometer especially if you plan on using it in the outdoors. Air pressure decreases with increasing altitude, but the actual air pressure is converted to its equivalent at sea level. In general, barometers in stores where you live should be calibrated for that elevation. And the most common altitude ranges are from 0 – 1500′ (0 – 460m) for more accurate barometers or 0 – 3500′ (0 – 1070m) for barometers suitable for general home use. Some manufacturers will offer barometers which will be reasonably accurate between 3500 and 7000 feet (1070 – 2130 m) – they may cost a little more. And at least one manufacturer (Maximum) supplies barometers calibrated to your choice of 10 different altitude ranges, ending at 11,000 feet+ (3350m), and at no additional charge.
There are two types of barometers – aneroid and mercury. The main difference between aneroid and mercury barometer is that aneroid barometer measures the atmospheric pressure using the expansion of a metal whereas mercury barometer measures the atmospheric pressure by adjusting the height of mercury inside a tube
Barometers being electronic and digital devices need protection, having a good waterproof case is an added value as it protects your barometer ensuring durability.
This will determine on what kind of barometer you want to use, in case of outdoor use, designs such as waterproofing and shock resistance are essential to consider when buying a barometer.
Q: What Is a Barometer?
A barometer is a scientific instrument used to measure air pressure. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.
Q: When Should I Use A Barometer?
Barometers can be used in outdoor activities such as hiking, whereby information such as altitude which is ever changing can be very useful. Barometers are also vital in activities such as fishing whereby atmospheric pressure plays a factor in the activity.
Q: How To Use A Barometer?
Setting up your barometer is easy. For an aneroid version, you need to manually calibrate it. All this means is using a small screwdriver to set the hand (like on a clock) to match the current barometric pressure in your location. Once you’ve done that, it’s all set. Digital barometers — usually included as part of a more comprehensive amateur weather station — do that part for you.
As we already learned, barometer measurements will either be in inches or millibars. Readings will generally be between 28 and 31 inches, usually measured to the hundredth decimal. Knowing just the number itself, however, isn’t all that helpful. What matters is in which direction the needle is moving. It’s the change in barometric pressure that helps forecast the weather.
A change in atmospheric pressure is just a way to predict weather; it affects life – though this fact is sometimes underrated. A key take is choosing the right barometer for the right purpose. Yes air pressure affects life but this is data that is not always a necessity to have in our everyday lives. However, there are cases when you need the data. Picture a day when you go out fishing, hiking Mt. Kilimanjaro or you are simply being your amateur meteorologist self – now these are the instances whereby the 10 Best Barometers in 2020 come in to play and they won’t disappoint!
