Kestrel 1000 User Guide

10
Impeller
The Kestrel impeller calibration drift is less than
1% after 100 hours of use at 16 MPH | 7 m/s. Drift
increases with higher-speed use. For most users, the
impeller will provide accurate wind speed/air ow
readings for years if not physically damaged. How-
ever, if your application requires extremely high
precision or if you perform frequent high-speed
readings, we recommend you replace your impeller
at one-year intervals. Every replacement impel-
ler is supplied with a certicate of conformity and
restores your Kestrel’s calibration upon installation.
Temperature Sensor (Kestrel 2000 and higher)
The Kestrel temperature sensor exhibits virtually
zero drift over time and generally does not require
recalibration for accurate performance during the
life of the product. If your industry or application
requires calibration, please contact NK or a certied
calibration lab for options and pricing.
Humidity Sensor (Kestrel 3000 and higher)
The Kestrel humidity sensor calibration drift may
be up to +/- 2% over 24 months. For high-precision
applications, we recommend recalibration at
24-month intervals. If you require calibration,
please contact NK or a certied calibration lab for
options and pricing. The humidity sensor may also
be recalibrated in the eld using a Kestrel Humid-
ity Calibration Kit (NK PN-0802). Instructions for
running the recalibration routine are provided with
the Humidity Calibration Kit and may also be found
at
Pressure Sensor (Kestrel 2500 & 3500)
The Kestrel pressure sensor drift may be up to 1
mbar over 12 months. For high-precision applica-
tions, we recommend recalibration at 12-month in-
tervals. If you require calibration, please contact NK
or a certied calibration lab for options and pricing.
The pressure sensor may also be recalibrated in the
eld with reference to a known-accurate and cali-
brated pressure standard. We do not recommend
simply recalibrating to a local weather station as this
may not be accurate for your location. Instructions
for recalibrating the pressure sensor may be found
at
