Buy a West and Company Banjo Barometer Online

Updated on December 9, 2012

Banjo barometers are the traditional shape of barometer we are used to seeing. Classy and timeless, they are an essential for any home because they not only look good, they are your early warning signal for a coming storm.

Most of them feature a thermometer too, but that is a throwback to the days when barometers used mercury which is sensitive to temperature change, so the person reading the barometer had to mentally adjust the mercurial reading taking the temperature into account.

Modern barometers for the home are generally aneroid, using a small box cell made from an alloy of beryllium and copper. The cell contracts or expands according to atmospheric pressure and a spring-loaded mechanism moves the needle on the face up or down.

The Banjo Barometer Thermometer Hygrometer in Deep Cherry by West and Company features a typical traditional American design in its solid wood mounting. Also features

  • German-made brass instruments with convex lens and brass overlay trim
  • barometer reads from 28"-31.9"/Hg (950 - 1050 millibars)
  • non-mercury thermometer with temperature range -10⁰ F – 120⁰ F (-12°C-50°C)
  • hygrometer with 0 - 100% RH
  • overall size of barometer - 22½” by 7¼”

Choose from low barometric elevation or high barometric elevation depending on where barometer is to be housed.

Barometers have to be adjusted depending on the height of your situation above sea-level. The higher you live, the lower the natural air pressure is and so for uniformity barometers are adjusted taking height into account so that all give a similar reading in the same geographical location.

In general, 1 inch of mercury is adjusted upwards for each 1,000 feet of height above sea-level. (the US and Canada still use the measurement 'inches of mercury',even though mercury is no longer used), or 1 millibar for each 8 metres in other countries.

The Banjo Barometer Thermometer Hygrometer in Dark Oak by West and Company has the same specifications as the Dark Cherry one above.

Color choice will be to suit your decor or taste.


The Banjo Barometer Thermometer Hygrometer by West and Company is also available in light oak wooden mounting.

Again this barometer has the same specifications as above, but the lighter color may suit your home environment better.

Why Buy a Barometer?

Barometers measure the air pressure around us which changes according to the weather we are experiencing, or are about to experience. If you ever watch the weather forecaston television, you will hear the forecasters talking about 'fronts' coming in, of high and low pressure. You will see weather maps with lines on them (isobars), denoting bands of atmospheric pressure.

Weather forecasting is difficult. It depends on so many factors, like air pressure, the amount of water vapor in the atmosphere, the proximity of mountain ranges, the activity of the seas, the gravitational pull of the moon, the season, geographical location, and the movement of the trade winds in the lower troposphere.

Barometers, however, are pretty constant. They fall when a cold front is approaching. They fall rapidly when astorm is approaching. The rise rapidly when the 'eye' of a storm is passing over.They rise slowly when calmer, better weather is coming.

Every home should have one. They all come with a hand that is stationary as well as the automatic hand/needle that moves automatically with changes in atmospheric pressure. This stationary hand can be moved by you, the user, to denote a reading, and then you can see at a glance if the pressure is rising or falling from where you last positioned the hand.

      They are the handiest things to have in the house. I've got one I've had for years and it still works perfectly. Nice to know when a storm is approaching.

      Thanks for stopping by :)
