Kestrel 4500 Anemometer - with wind direction - BUY ONLINE:
For years our customers have been asking for wind direction along with wind speed.The Kestrel 4500 anemometer does just that with its built in digital compass. But it doesn’t stop there. It also calculates crosswind and headwind/tailwind with reference to a user-set target heading, and stores the information along with all the other environmental readings in its 1400 data point memory.
For those with after dark requirements, the Kestrel 4500NV (with an olive drab case) is available with a low intensity red backlight to preserve night vision.
Pair the Kestrel 4500 anemometer with the optional Kestrel Vane Mount and you have a data-logging weather station that sets up in seconds and rotates in the slightest of breezes. Did we mention that the whole kit is the ultimate in portability? It packs down into a 2 x 6 inch pouch and weighs under 8 ounces.
The Kestrel Portable Vane Mount is an ingeniously simple accessory designed for extreme light weight and portability. The Vane Mount assembles in seconds and the precision pivot and lightweight vane extension allows the unit to spin freely in the slightest of breezes. The incorporated level
ensures that the Vane Mount is installed correctly and that direction readings will be accurate. Paired with the Kestrel's 2000 data-point memory log, extensive data can be collected including wind speed and direction.
Together, the Kestrel 4500 anemometer and Vane Mount weigh less than 8 ounces (227 g.) and pack into a compact 2 x 6 inch (5 x 15.25 cm) case. The Vane Mount can be affixed to any tripod or the Kestrel Lightweight Monopod for a complete weather station you can easily pack into remote locations.
The Kestrel Anemometer Kestrel 4500 anemometer
(with wind direction) is a small electronic rotating vane anemometer
with built in temperature sensor. It uses high precision jewel bearings
and a light weight impeller to provide accurate wind measurements even
at low speeds. The impeller is replaceable by the user in the case of
damage.
Like all
kestrel anemometers, the Kestrel 4500 anemometer power is from an easily
replaceable standard lithium coin type cell that will typically give
up to 400 hours of operation. The instrument switches off automatically
if no keys are pressed for 30 minutes.
The Kestrel
4500 anemometer is made from high impact injection moulded plastic and
corrosion resistant materials with the electronics fully sealed. It
will float if accidentally dropped into water. There is a hard cover
for protection when not in use and a lanyard is provided for added security.
TEMPERATURE
MEASUREMENT Kestrel 4500 Anemometer
The Kestrel 4500 anemometer / pocket weather station uses a precision
thermistor temperature sensor and like all thermometers time must be
allowed for it to obtain the same temperature as the air being measured.
However the special design of the Kestrel 4500 means that if there is
a good air flow over the sensor (by holding the Kestrel 4500 into the
wind) this will happen quickly. The 0.1-degree resolution of the display
aids in determining when a steady reading has been reached. These features
will be greatly appreciated by the user when measuring wind chill on
a cold windy day!
WIND
CHILL - Kestrel Anemometer 4500
The chilling effect of the wind can be represented by the lower temperature
that would be required to produce the same chilling sensation for a
person walking in calm conditions. This is known as the wind chill equivalent
temperature and is an important indicator in assessing the comfort of
personnel spending periods outdoors. It is not an indication that an
unheated inanimate object will cool below the ambient air temperature.
The Kestrel Anemometer 4500 will give an indication of the wind chill.
