Kestrel® Tune-up & Calibration Services

All of our measurements are traceable to the National Institute of Standards and Technology, ensuring the highest level of reliability. Our primary Calibration Standards are sent for calibration in accordance with NIST requirements and based on a regular schedule. Only approved laboratories and NIST themselves are used for these calibration services. 

Every Kestrel Pocket Weather Meter is individually calibrated and tested to be within specification at the time of manufacture as follows:

  1. Every wind impeller, including all replacement impellers, is individually wind-tunnel tested against a time of flight ultrasonic anemometer calibrated by NIST.
  2. Every humidity-measuring instrument receives a two-point NIST-traceable calibration and is verified at a third intermediate value against a factory-calibrated hygrometer.
  3. Temperature and pressure are functionally checked and verified against a NIST-traceable calibrated standard or reverified intermediary standard.

For many users, simple recalibration to original specifications, without certification or individual documentation, is sufficient.
For users who must ensure that their Kestrel is operating within specifications, we offer Factory Calibration and Certification services for any Kestrel

Field Calibration (Do It Yourself)

Kestrel Meters can be quickly recalibrated in the field, giving users confidence to rely on their Kestrel.
To field calibrate the wind or air flow readings, simply replace the impeller with a new one.
For relative humidity readings, use the RH Field Calibration Kit.
For pressure sensor calibration, check out the Knowledge Center, or contact our Customer Service Department for instructions.
The only sensor that cannot be field calibrated is the temperature sensor. The Kestrel’s accurate temperature readings are due to NK’s patented external thermistor, and over the 10+ years that we’ve been building Kestrels, we’ve never identified one that needed recalibration.


NIST Calibration Services (We send to our Lab in the USA)

All of our measurements are traceable to the National Institute of Standards (NIST) and Technology, ensuring the highest level of reliability.
Our primary Calibration Standards are sent for calibration in accordance with NIST requirements and based on a regular schedule.
Only approved laboratories and NIST themselves are used for these calibration services.

For users who must ensure that their Kestrel is operating within specifications, we offer Factory Calibration and Certification services for any Kestrel. For users who require documentation, we also offer fully-documented NIST-traceable calibration services.
Full before/after data is reported and shown on the calibration certificate. Instruments may be calibrated at the time of purchase or subsequently. 
The Kestrel must be retuned to our USA factory to perform this test, and so you will also be charged the cost of transport to & from USA (price depends on quantity).
If you wish, you can have your lab do it, we are more than happy to provide the information on how to calibrate the Kestrel.
