Kestrel 2500 Measures
• Current Wind Speed / Maximum Wind Gust / Average Wind Speed (mph, km/h, ft/min, m/s, knots and Beaufort)
• Temperature / Wind Chill (Fahrenheit and Celsius)
• Barometric Pressure (inHg and hPa (mb))
• Altitude (Feet and Meters)
Product Description
Kestrel 2500 Description
The Kestrel 2500 Hand Held Weather Meter measures barometric pressure plus temperature and wind velocity to deliver three-hour pressure trend indications allowing the user to predict future weather as well as receiving current accurate data readings.
If you are an outdoor enthusiast, hunter, climber, hill walker, extreme sports participant, skier, snow boarder or an agricultural professional wishing to predict as well as get immediate weather readings the Kestrel 2500 is the unit for you.
Note the Kestrel 2500NV has night-vision functionality allowing the user to see the data in a soft grey pink light preventing “bleaching out” and preserving the users night vision, reducing eye fatigue whilst minimising screen brightness thus preserving night operations.

Notes |
| Wind Speed or Air Velocity |
m/s | 0.1 | Larger of 3% of reading, least significant digit or 20 ft/min | 0.6 to 60.0 m/s 0.6 to 40.0 m/s |
1 inch diameter impeller with precision axle and low-friction Zytel® bearings. Start-up 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 start-up. Off-axis accuracy -1% @ 5° off-axis; -2% @ 10° -3% @ 15°. Calibration drift < 1% after 100 hours use at 16 MPH | 7 m/s. Replacement impeller (NK PN-0801) field installs without tools (US Patent 5,783,753). |

Air, water or snow temperature. 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 insulation effect. Calibration drift negligible. |
| °C | 0.1 | 1.0 °C | -45.0 to 125.0 -29.0 to 70.0 |
||
| Pressure | inHg | 0.01 | typical 0.04 inHg max 0.07 inHg |
0.30 to 32.48 inHg | Air pressure at the location. Adjustable reference altitude allows display of station pressure or barometric pressure corrected to MSL. Monolithic silicon piezoresistive pressure sensor with second-order temperature correction. Pressure sensor may be recalibrated at factory or in field. Kestrel 2500 and 3500 display continuously updating three-hour barometric pressure trend indicator: rising rapidly, rising, steady, falling, falling rapidly. Kestrel 4000 series displays pressure trend through graphing function. |
| hPa (mb) | 0.1 | typical 1.5 hPa max 2.5 hPa |
300.0 to 1100.0 hPa 10.0 to 1100.0 hPa | ||
| Wind Chill | °F | 0.1 | 1.8 °F | Refer to stated ranges for wind speed and temp. | Perceived temperature resulting from combined effect of wind speed and temperature. Calculated based on the NWS Wind Chill Temperature (WCT) Index, revised 2001, with wind speed adjusted by a factor of 1.5 to yield equivalent results to wind speed measured at 10 m above ground. Specification temperature limits established by WCT Tables. |
| °C | 0.1 | 1.0 °C | |||
| Altitude | ft | 1 | typical 50 ft max 98 ft |
-2,300 to 85,000 ft | Height above Mean Sea Level (“MSL”). Temperature compensated pressure (barometric) altimeter requires accurate reference barometric pressure to produce maximum absolute accuracy. |
| m | 1 | typical 15 m max 30 m |
-700 to 25,900 m | ||
| Max/Avg Wind | One-button clear and restart of Max Wind Gust and Average Wind measurement by powering down and restarting unit. | ||||
| Display & Backlight | Reflective 5 digit LCD. Digit height 0.36 in / 9 mm. Choice of aviation green or visible red (NV models only) electroluminescent backlight. Manual activation with auto-off. | ||||
| Response Time & Display Update | All measurements except those based on relative humidity respond accurately within 1 second. Relative humidity and all measurements which include RH in their calculation may require as long as 1 minute to fully equilibrate to a large change in the measurement environment. Display updates every 1 second. | ||||
| Clock / Calendar | Real-time hours:minutes clock. | ||||
| Operational & Storage Temperature Range | The operational temperature range of the liquid crystal display and batteries is 14° F to 131° F / -10 °C to 55 °C. Measurements beyond the operational range can be taken by briefly exposing unit to extreme conditions such that the display and batteries remain within the operational range. Storage range -22 °F to 140 °F / -30 °C to 60 °C. | ||||
| Auto Shutdown | After 45 minutes of no key presses. | ||||
| Certifications | CE certified, RoHS and WEEE compliant. Individually tested to NIST-traceable standards (written certificate of tests available at additional charge). | ||||
| Battery | CR2032, one, included. Average life, 300 hours. Battery life reduced by backlight use in 2000 to 3500 models. | ||||
| Environmental | Waterproof (IP67 and NEMA-6). MIL-STD-810F, Transit Shock, Method 516.5 Procedure IV; unit only; impact may damage replaceable impeller. | ||||
| Size & Weight | 4.8 x 1.9 x 1.1 in / 12.2 x 4.8 x 2.8 cm, 3.6 oz / 102 g (including slip-on cover). | ||||
