Kestrel 3000 Pocket Weather MeterThe Kestrel 3000 is the ONLY hand-held instrument for measuring wind speed, temperature, wind chill, relative humidity, heat index and dew point temperature. 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") 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 Humidity Sensor Response Time: 1 minute Resolution: 0.1 Environmental Sealing: Electronics enclosure IP67 - water resistant to 1 m (3') and floats Shock: Drop tested to 2 m (6') 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") 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") digit height Case: Slip-on hard case 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") 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. | ||
