KESTREL 3000 WIND METER WITH
TEMPERATURE/HUMIDITY/DEW POINT |
|
|
Kestrel
3000
· The Kestrel 3000 is the ONLY hand-held instrument for measuring
wind speed, temperature, wind chill, relative humidity, heat index
and dew point temperature.
· Pocket-sized and easy-to-use.
· Measuring modes and display units can be changed at any time.
· The large liquid crystal display is easy to read, even in low
light.
· The Kestrel 3000 measures wind speed with a large-diameter
precision ultralight impeller which turns on sapphire bearings.
· The impeller and protective housing pop out without tools for easy
and inexpensive replacement.
· The Kestrel uses an external thermistor for fast response and
accuracy to +/- 1.0ºC.
· The capacitive humidity sensor is factory calibrated to +/- 3%
accuracy and can be recalibrated in the field with our Relative
Humidity Calibration Kit.
· A hard slip-on case protects the Kestrel 3000 display, buttons and
impeller from damage.
· The Kestrel 3000 is covered by a full five-year warranty and is
also protected by US patent No. 5,753,784.
Features and Specifications:
Operating Modes: Moving 3-second average (), maximum 3-second gust
since power on (MAX) or average since power on (AVG).
Display Update: 1 second.
Units: Knots (KT), meters per second (M/S), kilometers per hour
(KM/H), miles per hour (MPH), feet per minute (FPM) and Beaufort
force (B).
On-Axis Accuracy: greater of +/- 3% or +/- least significant digit.
Off-Axis Response: -1% @ 5º, -2% @ 10º, -3% @ 15º.
Resolution and Range: KT, M/S, KM/H or MPH: resolution 0.1; max
display range 199.9.
FPM: resolution 1.0 below 1,999, 10 above 2,000(auto-ranging); max
display range 19,990.
Calibration Drift: < 2% after 100 hours use at 7 M/S (~14 KT, 25
KM/H, 16 MPH or 1,400 FPM).
Minimum - Maximum Speed: 0.3 M/S (~0.6 KT, 1 KM/H, 0.7 MPH or 60
FPM) to 40 M/S (~78 KT, 144 KM/H, 89 MPH or 7,830 FPM).
Operating Modes: Temperature; wind chill; relative humidity; heat
index; dew point temperature.
Units: Degrees Centigrade (ºC) or degrees Fahrenheit (ºF).
Accuracy: Temperature and wind chill, +/- 1.0ºC; relative humidity
+/- 3%; dew point temperature, +/-2ºC; heat index, +/-3ºC. Humidity
sensor can be recalibrated in the field.
Temperature/Wind Chill Display Update: 1 second.
Temperature Resolution: 0.1.
Humidity Sensor Response Time: 1 minute.
Humidity Resolution: 1%.
Environmental Sealing: Electronics enclosure IP67 - water resistant
to 1 m. (3 ft.). Floats.
Shock: Drop tested to 2 m. (6 ft.).
Operating Temperature: LCD readability is lost above 50ºC (122ºF)
and below -15ºC (5ºF). Accurate readings may be taken beyond these
temperature limits by exposing the unit for the minimum time
necessary to take and record measurement.
Storage Temperature: Recommended -20ºC to 80ºC (-4ºF to 176ºF).
Physical Buttons: Two sealed tactile rubber buttons control all
functions.
Auto Shutdown: 30 minutes after last key press.
Battery: User-replaceable CR2032 coin cell. Typical life, 400 hrs.
Impeller: 25 mm (1 in.) diameter, sapphire bearings, light weight.
User-replaceable without tools.
Temperature Sensor: Hermetically sealed precision thermistor.
Humidity Sensor: Silicon based capacitive sensor.
Display: Reflective 3 1/2 digit LCD, 9 mm (0.36 in.) digit height.
Case: Slip-on hard case.
Dimensions: 122 x 42 x 14 mm (4.8 x 1.7 x 0.6 in.); case, 117 x 46 x
19 mm (4.6 x 1.8 x 0.7 in.); lanyard, 0.5 m. (10 in.).
Weight: Unit, 44 g. (1.6 oz.); case, 23 g. (0.8 oz.).
Temperature Limitations:
The Kestrel temperature sensor is able to measure temperatures as
low as -30C (-22F) and as high as 70C (158F). The sensor and
electronics simply won't measure beyond this range. The Kestrel is
able to display wind chill measurements lower than -30C, depending
on wind conditions. It is also able to display heat index
measurements above 70C, depending on humidity conditions.
Furthermore, the Kestrel display will not function if the display
itself gets below -15C. However, if the unit is kept in a pack or
pocket or other warm area, the display itself should not get this
cold. In other words, try not to leave the Kestrel outside in
temperatures below -15C.

YEAR WARRANTY on entire system, covering manufacturing
defects. |
