Kestrel 2000 AnemometerThe NK Kestrel 2000 Thermo- Anemometer is a pocket-sized precision instrument for measuring wind speed, temperature and wind chill. It's ready when you are...just slip off the protective case and press "ON" for fast, accurate readings of the environmental conditions that affect you most. The large liquid crystal display is clear and easy to read under almost any conditions.
Dimensions: Wind Speed Functions Operating Modes: Moving three-second average (wind speed), average since power on (AVG) or maximum three second gust since power on (MAX) 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 (B) On-axis Accuracy: +/- 3% of reading or +/-least significant digit, whichever is greater Off-axis Response: - 1% @ 5 °, -2% @ 10 °, -3% @ 15 ° Calibration Drift: <2% after 100 hours operation at 7 M/S Minimum Speed: 0.3 M/S (~0.6 KT, 1KM/H, 0.7 MPH, 60 FPM) Maximum Speed: 40 M/S (~78 KT, 144 KM/H, 89 MPH, 7830 FPM) NOTE: Extensive operation at or near maximum speed may result in impeller bearing wear and reduced accuracy. Temperature/Wind Chill Functions Operating Modes: Temperature, wind chill Update: 1 second Units: Degrees Centigrade (°C) and degrees Farenheit (°F) Accuracy: +/-1°C Resolution: +/-0.1°C temperature, +/-0.1°C wind chill Other Function 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 hours Environmental Specifications Sealing: Electronics enclosure IP67 - water resistant to 1meter (3') and unit floats Shock: Drop tested to 2 meters (6') Operating Temperature: LCD functional temperature range, -15 °C to 50 °C (5 °F to 122 °F) Storage Temperature: Safe storage temperature range, -20 °C to 80 °C (-4 °F to 176 °F) Physical Specifications Impeller: Diameter 25mm (1") High precision jewel bearings User replaceable impeller assembly Temperature Sensor: Hermetically sealed thermistor Display: Reflective LCD, 9 mm (0.36") digit height Case: Slip-on hard case protects display, buttons and impeller Dimensions: Unit: 122 x 42 x 14 mm (4.8" x 1.7" x 0.6") Case: 117 x 46 x 19 mm (4.6" x 1.8" x 0.7") Lanyard: 0.5 m (10") Weight: Unit: 43 grams (1.5 oz) Case: 23 grams (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. | ||
