The
Kestrel 2500NV
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.”
This
model includes NV Configuration
Military
personnel and pilots flying in darkness are often
concerned with preserving their night vision.
Due to overwhelming demand from our military customers,
the Kestrel NV line was added in 2005.
Note:
The Kestrel 2500NV has a night-vision preserving
backlight which helps users to sustain natural
night vision. The NV’s backlight incorporates
an optical filter to reduce overall brightness
and minimize blue and green spectrum light to
preserve night vision. Additionally, NV backlights
are also much dimmer than a standard backlight,
making it more difficult to detect with the naked
eye in night operations. This backlight appears
soft greyish pink, not red, and is still in the
visible spectrum, so is not compatible with night-vision
equipment.
It
takes 30 to 45 minutes for the average eye to
adapt to darkness and maximize night vision. Even
a short burst of white, yellow, green or blue
light “bleaches out” the rod cell photoreceptors
in the eye and causes night blindness until the
entire adaptation process can take place again.
Light in the red spectrum does not cause this
“bleaching out”, preventing night blindness and
night vision fatigue.
Certified and Guaranteed Accuracy
Every single Kestrel manufactured at Nielsen-Kellerman
is calibrated for every single value, either directly
against NIST-traceable standards or against an
intermediary standard that is calibrated daily.
Every unit is shipped with a FREE Certificate
of Conformity that states what calibrations were
performed, and the certified performance specifications.
What does that mean for the customer?
They can be absolutely sure that their weather
readings are accurate to the stated specifications.
Some competing weather instruments claim the same
specifications as Kestrel, but only Kestrel certifies
their accuracy. What does that mean for the customer?
