3000

Pocket Weather ® Meter

with Backlight

Thank you for purchasing the Kestrel 3000 Pocket
Weather Meter. This instrument will measure the following
environmental conditions:

• wind speed • wind chill

• maximum wind gust • relative humidity

• average wind speed • heat stress

• temperature (air, water, snow) • dewpoint

This instrument also features a data hold function, a backlight,
and an automatic power-down function. Every unit is
fully tested at our factory for measurement accuracy and
waterproof integrity.

UNDERSTANDING THE MEASUREMENTS

Wind Speed - average over the previous three seconds. The measurement will be accurate

for air ow through the front or rear of the unit.

Maximum Wind Gust - maximum 3 - second wind speed since the unit was turned on.

Average Wind Speed - average wind speed since the unit was turned on.

Temperature - instantaneous temperature of the thermistor, which is located at the end

of the long coiled leads in the open cavity below the impeller. The exposed thermistor will
respond quickly to changes in temperature when air ows past it. For fastest response, either
hold the unit into the wind or wave the unit side to side for 15 seconds. Readings should be
taken in the shade. Water and snow temperatures can be taken by hold the unit in the water
or snow.

Wind Chill - combination of wind speed and temperature, as dened by the US National
Weather Service. Wind chill is the eective temperature on a human or animal at low
temperatures due to wind speed. Wind chill readings will be the same as the temperature
readings above 45ºF or below 3 mph.

Relative Humidity - amount of moisture in the air compared to the amount of moisture the
air can hold for the given temperature, represented as a percent. Because relative humidity is
also a function of the temperature, the response time will be dependent on the temperature
response time (see temperature section above). Readings should be taken in the shade.
