3-in-1 Imperial Weather Station 5.2'' Dial Mechanical Barometer for Boat | Imperial Fahrenheit Scale, Precise Weather Prediction, Metal Housing, Horizontal & Vertical Wall Mount (Model AW007A)

I've had this since early 2020 and have now used it in two different residences without a problem. It hangs on the wall, and not too high so the temp/humidity gauges don't get affected by the height and it being warmer. I use the barometer everyday a LOT and have it calibrated to wunderground.com which I also have used for decades for its accuracy. I adjusted just now and initially when I first got it years ago, and it's my reference to weather every day! I can tell if it'll be cloudy as the barometer pressure drops, or gets clear and sunny as the pressure increases. There's even a dial marker you can turn as a reminder as to when last set, to compare to a more timely reading. I've read the other reviews and am guessing others really don't know HOW read it. The pressure does NOT really change much, unless you have a hurricane or tornado coming your way, then it should drop in pressure waaay down! In the two different locations I've been, I have had NO problems at all, adjusting it as necessary [tool provided] and it has been accurate in all aspects: humidity, temperature and barometer pressure, and this is the very first and only one I've ever owned. I later purchased a handheldd wind/temp/pressure reader which is VERY handy to use also. As a photographer who ventures out in all sorts of weather, these weather and barometer instruments are very useful. I have had NO problem with this , and for those who know how to calibrate it with the included tool, will be a very useful tool for them, as it has been through the years for me. I highly recommend this, and I have NEVER had a problem with this throughout the many years I've had this.

A good looking barometer for the money. Works pretty well. A bit fidgety to adjust initially. My only real complaint is that the telltale needle is hard to move because the adjustment knob is pretty small and hard to grasp. Pretty much I am satisfied with the purchase.

I was uncertain about getting a barometer at all after looking at multiple reviews (for multiple different barometers); so many reviews say they are unreliable. However, after getting this one and setting it the way the instructions said, it has given the same readings as a local weather station every day for the past two weeks. I pick it up and tap gently to let the needle swing around some but it's final stop is always very close to what the local weather station says. So I have been very pleasantly surprised by the accuracy of the barometer part. The thermometer also seems to be accurate. I am not as sure about the hygrometer, because I have another hygrometer and they seem to disagree with each other most of the time. But the needle definitely moves and I can see when it is more humid or less humid; but whether the actual numerical reading is accurate or not with the hygrometer I cannot tell. Overall I'm very satisfied with this item and it is nice to have all three meters in one.

This barometer flat out does not work. I’ve set it and carefully placed it on the wall and in 2 weeks with major swings in actual barometric pressure changes it never moved. I’ve tapped lightly on the wall next to it, no movement. I’ve lightly tapped it, still not working. I’ve recalibrated it several times and it does not move at all. Last time I set it the altimeter setting was 30.05 and today it is 29.74, but the stupid thing is still holding steady at 30.05. A broken clock is least correct twice a day. This thing is only correct the exact moment you calibrate and then never again. Don’t waste your money.

I didn't purchase this for accuracy. I purchased it for one simple purpose. I have discovered that severe increases in atmospheric pressure trigger sinus headaches. I know that we see a sudden drop, a sinus headache is on the way, and if I can know it's coming, I can take steps to avoid it. It does it's basic purpose, but it is just annoying that you have to tap the glass to get it to respond. I guess from now on, when I check it in the morning, I'll just automatically tap the glass. Yesterday was the first big test. I didn't see a forecast for rain, and it was actually day two of having it mounted. I was surprised to see that when I tapped it, the needle dropped significantly. Well, I wouldn't have even noticed had I not intentionally tapped the glass to see if it was working, and sure enough, it got really windy with an extreme pressure spike later on in the day. Once again, I had to tap the glass to get the barometer needle to accurate respond to the change. So yeah, it does work. It's not going to suit my purposes, though, as it is mounted in a place that's not easy to tap, so I guess I'll be keeping the stepping stool handy while searching for a replacement.

I was a little worried about buying this because there were reviews that said the barometer did not work. I think they misunderstand how an aneroid barometer works. This is not digital. It is composed of an evacuated chamber which flexes based on the external air pressure, and that flexing drives a gear that moves the dial. When you use one, you HAVE to tap on the front lightly to allow it to settle to the current pressure. Mine was a little out of calibration, but you just turn the screw on the back slightly to adjust. Sometimes, it can take days or weeks to see a pressure change if you are in a period of stable weather. This does not mean it does not work. It means it is telling you what you want to know: stable weather. And if it is not quite exactly on the actual true pressure, that doesn't matter anyway. The real value and purpose of a barometer is to show CHANGE, not absolute value. Falling pressure implies worsening weather, rising pressure implies improving weather. And if it changes a LOT in a very short time (1 or 2 days), it implies a significant weather event is coming. All three dials - barometer, temperature, and hygrometer - are all within an acceptable tolerance. This is a great deal and very nice quality.

Beautiful design and looks amazing. The Barometer, why I bought the item, is accurate and can be calibrated. I adjusted it once and it's matched actual pressure. The temperature and humidity are way off and not able to be calibrated. I am sure it's not 65 degrees in my office right now. But, for the pressure (large dial) it's great! So 3/5.

Some might wonder why the pressure scale if off about 10° from vertical. That's because 29.92 inches of mercury is standard barometric pressure and is displayed at the top on this particular model. I found the device fairly easy to calibrate with the tool provided. I used the NOAA observation to set it to my elevation. Android barometers are kind of gimpy so you have to give it a little tap to make the needle display the accurate pressure. The unit in my photo is mounted on a slab of bass wood.

Bought for my dad as a gift and he uses it in his home in Auckland. Lack most of these types of devices they are reasonably accurate but not tremendously. Works fine so long as you give it a few soft taps to let the needle settle in the right position.
