Kestrel-2500 - Pocket Wind Meter

The Kestrel 2500 takes the great features of the Kestrel 2000 and adds in a pressure sensor. A three-hour pressure trend indicator helps you predict fish and wildlife activity and know when the weather's going to turn nasty. With its easy-to-use digital pressure altimeter, you have the perfect instrument for any outdoor activity.In addition to predicting weather activity, barometric pressure also influences a bullet?s trajectory, which is why the Kestrel 2500 is used by shooters and hunters when accuracy is important. US Olympic Rifle Champion Shooter Lones Wigger wouldn?t trust any other instrument. ?The Kestrel Meter is essential for target rifle shooting. It helps me win matches, and I rely on it for accurate weather information.?Kestrel 2500 Measures * Current Wind Speed * Maximum Wind Gust * Average Wind Speed * Air, Water & Snow Temperature * Wind Chill * Barometric Pressure * Altitude Kestrel 2500 Features* Real-time clock * Protective cover with sure-grip overmolding * Data hold function * Large easy-to-read display with backlight * Waterproof and floats * Innovative design for stability and accuracy in abrupt condition changes * Patented user-replaceable impeller * Quick response, external thermistor * High precision pressure sensor * Reliable, portable and easy to use * All instruments and accessories are completely assembled in the USA * 5-year warranty Kestrel 2500 Includes* A slip-on protective cover * Neck lanyard * CR2032 coin cell battery (Average life 300 hours) * Kestrel Certificate of Conformity Measurement Response TimeUnits Operational Range Resolution Accuracy (+/-) Specification Range Wind Speed 1 second m/s0.4 to 60.0 m/s0.10.4 to 40.0 m/sft/min59 to 11,948 ft/min159 to 7877 ft/minkm/h1.0 to 218.0 km/h0.1Larger of 3% of reading or least significant digit1.0 to 144.0 km/hmph0.8 to 135.0 mph10.8 to 89.0 mphknots0.6 to 118.3 kt0.10.6 to 78.0 kBeaufort0 to 12 B0.10 to 12 B1 inch diameter impeller with precision axle and sapphire bearings.  Off-axis accuracy -1% @ 5? off-axis; -2% @ 10?; -3% @ 15?.  Calibration drift < 1% after 100 hours use at 16 MPH / 7 m/s.  Sustained operation above 60 MPH / 27 m/s will wear impeller rapidly and may cause destruction of impeller.  Replacement impeller (NK PN-0801) may be field-installed without tools (US Patent 5,783,753).Temperature 1 second?F-49.0 to 257.0 ?F0.11.8 ?F-20.0 to 158.0 ?F?C-45.0 to 125.0 ?C0.11.0 ?C-29.0 to 70.0 ?CMeasures air, water and snow temperature.  Thermally isolated, hermetically sealed, precision thermistor mounted externally (US Patent 5,939,645).  Calibration drift negligible.Pressure 1 second   (mb & PSI 4000 model only)inHg0.3 to 32.5 inHg0.010.05 inHgAt 77.0 ?F, 22.1 to 32.5 inHghPa / mb10.0 to 1100.0 hPa / mb0.11.5 hPa / mbAt 25.0 ?C, 750 to 1100 hPa / mbPSI0.15 to 16.0 PSI0.010.02 PSIAt 77.0 ?F, 10.9 to 16.0 PSIMonolithic silicon piezoresistive pressure sensor with second-order temperature correction.

Warranty: 5 YearsHave you seen a cheaper Grey Import online? You need to read this before purchasing: Kestrel meters from the USA do NOT come with a C-Tick, which is required to be imported to AU.Warranty without a C-Tick will not be covered through the AU distributor/Reseller and will not be their responsibility. In order to receive a unit with the required C-Tick, you must purchase it from an authorized Australian retailer/distributor. You cannot purchase these meters in the USA or anywhere else. If a meter is shipped to you from the USA, you risk the meter being destroyed at customs.All Kestrel meters supplied by Instrument Choice come with a C-Tick and we offer the full 5 year warranty#isolation-scope-ifi9rqq3bvq79gd74ybc40686 #iulw{width:100%;} #isolation-scope-ifi9rqq3bvq79gd74ybc40686 #igyq{text-align:left;vertical-align:top;} #isolation-scope-ifi9rqq3bvq79gd74ybc40686 #ivo9wj{text-align:left;vertical-align:top;width:15px;} #isolation-scope-ifi9rqq3bvq79gd74ybc40686 #i1h18p{width:275px;text-align:right;vertical-align:top;border-width:0px;border-style:solid;}
