Recalibration Recommendations:
Kestrel Humidity Sensor
- Can drift up to +/- 2% for every 24 months.
- This is independent of whether or not the Kestrel is being used.
- Recommend every 2 years to stay within specs.
Kestrel Wind Sensor (Impeller)
- Drift is < 1% after 100 hours use at 16 MPH.
- This is dependent on usage.
- Recommend purchase new impeller every 2 – 3 years based on usage.
Kestrel Temperature Sensor
- Sensor will have negligible drift during the life of the product.
- Should not need recalibration.
Kestrel Pressure Sensor
- Sensor will have negligible drift during the life of the product.
- Can be recalibrated in the field with a known reference source.
- Contact NK before adjusting System Barometric Pressure however.
