NEW!
All Kestrels now have a 5 YEAR WARRANTY
The Kestrel 3500 Pocket Weather Meter is a small, pocket-sized electronic
rotating vane type of anemometer (wind meter) with built-in temperature, humidity and
barometric pressure sensors. It uses high precision jewel bearings and a
light weight impeller to provide accurate air flow measurements even at low
speeds. The impeller assembly is replaceable by the user in the case of
damage.
A trend arrow displays whether the pressure is rising, stable or falling,
this trend is calculated over a 3-hour period. The pressure is monitored
even when the 3500 is switched off.
Wind chill and heat index are equivalent temperatures that show the user
how their environment really feels. Wind chill is the combination of wind
speed and temperature, while heat index is the combined effect of air
temperature and relative humidity. The humidity sensor compensates for
temperature changes and is designed for stability and accuracy.
The liquid crystal display has large 9mm high digits and is backlit for a
clear readout in low light conditions. For users with after dark
requirements, the new Kestrel 3500NV, with an olive drab
case, has a lower intensity red backlight
to preserve night vision.
Power is from an easily replaceable standard
lithium coin type cell, which will typically give up to 400 hours of
operation. The instrument automatically switches off if no keys are pressed
for 45 minutes.
The Kestrel 3500 Pocket Weather Meter 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.
