Calibrating Your Barometer

Our president at Weems & Plath, Peter Trogdon, takes time to show how to calibrate a few of our barometers. This video is helpful in showing how to determine what the pressure of the barometer should be set to and how to adjust it.

Thanks Peter most helpful we have a Cyclone currently brewing off the coast of Queensland Australia I'll be watching for the changes on my analog weather station Happy New Year

Thank you Peter, pressure tested an oldie that'd been kicking around, a Taylor, now can calibrate!

Would like to point that official local pressure may not be the same to your actual location. Pressure fluctuates depending of a few factors such as winds and elevation. Speaking of mechanical barometers, one issue is that after many years, the small pivot of the indicator gets surface rust from the humid air and starts getting stuck. One may want to lubricate this pivot with a very light oil, however access is often difficult because most units are sealed and cannot be opened.

In the US, weather forecasts are amazing, I lived there a couple of years, even broadcasts to like 10 days ahead are done with a lot of accuracy. In Europe, central Europe even, my God it is bad...people here can't even predict two days ahead, no joke. Best weather forecast you have here is having your own barometer.

How can you tell atmospheric pressure with a radio?

[marcozompanti]

Thank you so much. I’ve changed home and I thought my barometer was broken.

[fredchapman]

Thanks! I do it daily as pressure changes?

Great vidio... can you tell me why I have 3 pointers o my barometer red black silver.

Just calibrated the Schatz barometer I bought on Craigslist for $25 - thought it was broken before finding this video.

Is it best to calibrate barometers when the atmospheric pressure is in the middle of the barometer’s measuring range? I calibrated mine when the atmospheric pressure was about 29.42 inHg and now it’s off when it’s 29.79 inHg. In know all instruments have some error and was just wondering if the middle range would be the best sweet spot.

[Peppermint]

Worth mentioning that most of the time bad weather does not cause a barometer drop. Small systems bring rain/snow/clouds without a drop in the atmospheric pressure, in fact these small systems may actually cause an increase in atmospheric pressure. It's mostly the larger systems that will cause a pressure drop. In other words., most of the time these barometers are worthless.

Very helpful video -- succinct and "just the facts" -- Thank You!

What is total workdone by this aneroid barometer in terms of energy in joules

[Whisperin]

if your barometer is at some hight like it is on the ships usually 25 m above sea lever, how we calibrate for that ?

[newwavepressure]

I bought a decoration one that looks like a steering wheel ship.. I want to keep it inside wood air conditioning give me a false reading???? does it need to be

[sunflowerheather]

I have my grandfathers salem bells barometer. It doesnt have a set needle. How do i calibrate it? Thank you

[anilsharma-evmy]

How much workdone by barometer ? In joules?
Aneroid barometer do how much work in joules?
If we make a bigger models then will it turned a turbine or not ?

The purpose of a barometer calibration is to detect atmospheric pressure perturbation resulting from a change in weather.

Question: I got a fishing barometer. Pretty similar settings and look; metal case, etc. There are two needles: (1) the one you adjust with the screw as you were showing and (2) on the glass. What's the one on the glass for and does need any adjustment? Thanks

[billcosby]

Very informative, thanks for the video!
