| Accuracy (+/-): | Larger of 3% of reading, least significant digit or 20 ft/min |
| Notes: | 1 inch|25 mm diameter impeller with precision axle and low-friction Zytel® bearings. Startup speed stated as lower limit, readings may be taken down to 0.4 m/s | 79 ft/min | 1.5 km/h | .9 mph | .8 kt after impeller startup. Off-axis accuracy -1% @ 5º off-axis; -2% @ 10º; -3% @ 15º. Calibration drift < 1% after 100 hours use at 16 MPH | 7 m/s. Replacement impeller (PN-0801) field installs without tools (US Patent 5,783,753). Wind speed calibration and testing should be done with triangle on impeller located at the top front face of the Kestrel. *F/S only in Ballistics units. Beaufort not available in Ballistics units. |

| Notes: | Hermetically sealed, precision thermistor mounted externally and thermally isolated (US Patent 5,939,645) for rapid response. Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. Calibration drift negligible. Thermistor may also be used to measure temperature of water or snow by submerging thermistor portion into material -- remove impeller prior to taking submerged measurements and ensure humidity sensor membrane is free of liquid water prior to taking humidity-based measurements after submersion. |

| Notes: | Monolithic silicon piezo-resistive pressure sensor with second-order temperature correction. Between 1100–1600 mbar, unit will operate with reduced accuracy. Sensor may not operate above 1600 mbar and can be damaged above 6,000 mbar or below 10 mbar. Calibration drift is negligible for the life of the product. |

Nature can turn on you at a moment's notice.
Predict fish and wildlife activity as well as when bad weather is headed your way with the three-hour pressure trend indicator. With its easy-to-use digital pressure altimeter, you have the perfect instrument for any outdoor activity - get conditions in seconds right in the palm of your hand.
In addition to predicting weather activity, barometric pressure also influences a bullet’s trajectory, which is why the Kestrel 2500 is used by hunters when accuracy is important.
Available Orange (2500) with a standard backlight or in Olive Drab (2500NV) with Night Vision Preserving Backlight: The Kestrel 2500NV in Olive Drab with night-vision preserving backlight helps users to sustain natural night vision.

QUESTIONS & ANSWERS
Ask a Question-
The Kestrel 2500 weight is stated as 102g. Does that weight include or exclude batteries.
We weighed in the Kestrel 1000-3500 series meters with lanyard, slip-on hard case, including the installed battery at 3.8 ounces

I have a 2500 serial no. XXXXXXX. The wind fan is broken. Can it be replaced? Could I get the part and replace it myself? How much for the part if so. I don\'t know how long I\'ve had it but am doubtful that it is still under warranty. It was not dropped, but the fan just came apart.
I have good news for you! If your meter looks like models we have on our site, the impeller is replaceable. The entire black section can push out and a new one pushed in. You can find the impellers here: Kestrel user replaceable impeller.
-
Does the 2500 record min max temperatures like the 2000 does?
Both the 2000 and 2500 record max and average wind speed and wind chill but not min, max, temperature. For that, you would need a Kestrel 5 series weather meter.

I am looking to get a somewhat accurate barometer to read pressure and was wondering about the Kestrel 2500, what units will it display for pressure and temperature, and how accurate are they?
The pressure units which can be changed are inHg, hPA and mb. For accuracy, see Kestrel 123 Series Certificate of Conformity & Sensor Specifications on our Resources page

I’ve owned a kestrel 2500 wind meter for years I’ve used it to great success in my application of long range hunting but the battery cover has broken. I would like to see if I could purchase a new cover I don’t wish to replace the hole unit I have really In joyed this product

I'm looking for an instrument that will give a ten minute wind speed average. Will this model ( Kestrel 2500 ) do that? if so what is the process to get it on and from the instrument?
The 2500 will record the average wind speed for as long as it is on. When you turn it on, it will start recording the average wind speed. It will report it on the screen. If you want something to actually record, log and be downloadable, check out the Kestrel 5000 or Kestrel 5500 weather meters. Both store data which can be downloaded either wirelessly (LiNK enabled models only) using the Kestrel smartphone LiNK app or with the help of the Kestrel USB Data Transfer Cable to a PC or MAC.

Hi, I was interested in finding out more information about your Kestrel 2500 weather meter, specifically the units and accuracy of the barometric pressure that it displays, can I change the units of the barometric pressure? Also does it measure air temperature? How accurate is it?
The 2500 as all Kestrel Meters are extremely accurate. There are no cheap sensors used in a Kestrel. The pressure units which can be changed are inHg, hPA and mb. They are made right here in Pennsylvania, are waterproof and float. They are meet mil drop test standards. The 2500 measures Wind speed, Temperature and pressure.

I need to order 3 Kestrel 2500 Handheld weather devices for the Government. Can I order these tax fee?
Yes, At this time, we are only required to collect sales tax to shipments to PA.

My battery "door" is broke, a tab fell off. It is a 2500. Do you sell that part, and if so let me know the details so I can get it going. Thanks
Hi, sorry about your battery door. We do have them here: Kestrel 2500 Battery Door in Orange

I'm need a NIST certified wind speed sensor - the Kestrel 2500 looks perfect (the additional sensors might be useful to us.) What is the lead time with the calibration?
You would need to purchase the meter and NIST calibration at the same time. The lead time for calibration is anywhere between 5-7 business days.
-
what is the size and weight of the Kestrel 2500 Handheld Weather meter? Are batteries included in the Kestrel 2500 Handheld Weather meter?
Hi! The Kestrel 2500 weighs in just under 4 ounces. This includes the lanyard, slide on case and meter itself. It is 1" thick x 2-7/8" wide x 5" long (inches). Dimensions are of the meter inside slip-on case. The case is not much larger than the meter itself though. The Kestrel 2500 uses one CR2032 lithium battery. One battery is included inside the meter. Thanks!
