Kestrel 5500

Pretty accurate device. The only issue is that the air temperature reading is slow to adjust when the winds are calm, especially if you take the device from inside a warm house out into the cold. Point the thermistor into the wind and the temperature will adjust more quickly. Update: I recently visited the summit of Mt. Washington and got to test this Kestrel meter. The altimeter and barometer adjusted perfectly as we ascended the auto road to the summit at 6288'. Works fine at 800 millibars and in strong winds. Altimeter matched the altitude marked on poles along the road.

Updated Review: 7/7/2025 I recently repurchased this unit for Christmas. This is about the most accurate weather sensor you can get. It is better than my AccuRite weather station. There are almost no other weather stations on the market that allow data to be transmitted by Bluetooth. The build quality of the '5500' is fantastic. It feels like you are holding a Nokia phone. It is extremely durable. The impeller is also replaceable, so if it does get damaged you can just switch it out with a new one. It can be a bit tricky to calibrate the compass, but if you watch some online tutorials it is doable. Everything about this is astetically pleasing. The impeller cover clicks into place, the buttons click nicely. Its built like a tank. It definitely is worth it to get the LiNK enabled Bluetooth model. I'm going to post my final review first, below was my initial review: The product is well built but it doesn't do enough for something that costs over $400. I would expect an integrated GPS at least. The product is well made and there is nothing wrong with it other than it is insanely expensive. My phone can tell my altitude and barometric pressure better than this can. The altitude is also frequently wrong (again it needs GPS for better accuracy). It is also only slightly more accurate than other cheap 20 dollar sensors. My initial review: For 400 dollars for a weather sensor I expect the best. The plastic film that covered the sensor was scratched (thankfully not the actual screen) out of the box and there were plastic hairs next to the buttons. I also saw logs from 2021 as well which either means they were logging in the factory and testing it or I was sold a used product as new. I think it was tested though based on the measurements. Its accurate but takes way too long to cool down. One of the selling points is that it takes a few seconds to take accurate measurements. Also the lithium battery is only half full per the indicator out of the box. It was also very cold when it was delivered. After using it for a day it is more accurate and faster to cool down than my Protomex which was 20 dollars. It really feels like a Nokia when you are holding it. Its solidly built. Everything that moves feels sturdy including the battery door and cover for wind protector. The propeller sounds a little brittle but that might just be the design and it works well. For some reason it is not taking a regular Energizer Max battery it only takes the liion version which are very pricey. The return is taking a lot longer than expected.

Kestrel 5500 weather station arrived quickly from Amazon. Instructions were through and clear. This is a very high quality professional level instrument. Some reviews cite a lack of instructions. My device came with complete instructions. Kit included the carrying case; the 5500; a lanyard; a lithium battery; a weather vane kit for mounting the device to a tripod so it free wheels into the wind; and a link capability to bluetooth link the 5500 with a mobile device or PC. It also has a port for a wired connection to a PC. I found the device easy to use after spending about 30 minutes learning the simple menu system. You can customize a 3 row initial screen with measurements of your choice or scroll down to look at them individually. Some people are confused by the station pressure vs barometric pressure. Station pressure is the actual pressure at your station. As an example, my site is about 4300 feet above sea level. Station pressure in this case is the actual atmospheric pressure adjusted for the elevation since less air is above my site. It typically reads something like 25.xx inches of mercury for station pressure instead of 29.xx inches of barometric pressure. Pressure change is the most important thing to keep in mind and that change will ripple into both barometric and station pressure. You may find atmospheric pressure given both ways on some internet sites depending upon the site. Typically barometric pressure is more common and provides a simple way to track pressure changes. I've found that pressure going up causes wind as does pressure going down. Pressure going down is indicative of a low pressure storm moving in and increasing pressure indicates warmer weather coming. One needs to use the app for mobile devices to pair the 5500 with your mobile device via bluetooth (assuming you have the 5500 with link). I tried paring it without using the app and it would not connect. Just scroll thru the multiple screens on the app after it is loaded and you will get to a page where it allows you to connect to your mobile device. The Kestrel web site has great instructions on pairing as well. I hope this review helps to clear the air on this very powerful device.

This is the best portable weather station out there.

Kestrel is a name brand high quality precise piece of equipment. What can I say. They nailed it! They have so many options with so many features. It took me about 6 months to decide on what one I wanted/needed for my application. I just went with what I needed with the option to expand. This thing has it all, everything I could ever need for windspeed. I upgraded from a $59 unit from 10 years ago to this and I am so glad I did. I HIGHLY recommend Kestrel no matter your application because they make it. Like I always say, If it doesn't say Kestrel on the box, someone else makes it and Kestrel STANDS BEHIND THIER PRODUCT.

Product as advertised. I used for many months now. Battery lasts great! I retrieve data over optical cable for analysis on the macOS - no problems there.

I got this just before going on long trip abroad and could not thoroughly test it. When I came back and tried it out, the impeller got constantly stuck, producing clicking sounds and of course recording much too low wind speed readings. I contacted support and was told to nudge it away from the casing, but I could not even tell where it touched. To get a better look I decided to remove the impeller from the instrument, which is normal procedure for replacing it and described in the manual. It came out and fell apart as you can see in the photo. It is a really cheap looking frail plastic part. You should know that they sell replacements for between 30 and 40 Euros including tax and shipping and it is supposed to be calibrated in a wind tunnel and come with a certificate. This is absolutely ridiculous. And it also proofs that it is not made to last. Why make it so easily replacable otherwise? Support told me to send it back to Amazon (which is not possible anymore) instead of offering at least a free replacement impeller. The only thing Kestrel is good at is marketing to sell their cheap quality product for a ridiculously high price.

Nothing to complain about with this weather Meter. Well built, accurate and easy to use. Still learning how to log and graph my readings though.

Puededen facturar la compra??

This guys are awesome. The kit is too!

Excellent produit
