Please note: These units will come with a "Certificate of Conformance" from Kestrel, however, in general this does not constitute a formal calibration certificate.
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.

Kestrel Meters are designed and manufactured at NK?s facility in Boothwyn, Pennsylvania, and are individually calibrated at the time of manufacture. Every Kestrel Meter comes with a Certificate of Conformity to document the unit?s accuracyall Kestrel measurements are traceable to the National Institute of Standards and Technology, ensuring the highest level of reliability.
Warranty: 5 Years
Have 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

1 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). |
