Specifications
| Measurement | Units | Accuracy | Range |
| Current, Max and Avg Wind Speed | m/s, km/hr, mph, fpm, kts, Beaufort Force | ±3% of reading or ±0.1 m/s |
0.3 to 40 m/s (0.7 to 89 mph) |
| Temperature, Wind Chill, Heat Stress, Dewpoint | °C, °F | ±1°C (±2°F) | -29 to 70°C (-20 to 158°F) |
| Pressure | hPa, inHg | ± 3 hPa | 870.0 to 1080.0 hPa (25.70 to 31.90 inHg) |
| Altitude | feet, meters | ± 30 meters (at standard atmospheric conditions) |
-500 to 9000 meters (-1500 to 30000 feet) |
| Display Update | 1 second | ||
| Display Size | Reflective 3 1/2 digit LCD, 9 mm (0.36 in.) digit height | ||
| Off-Axis Wind Speed Accuracy | -1% @ 5º off-axis; -2% @ 10º; -3% @ 15º | ||
| Calibration Drift | < 2% after 100 hours use at 7 M/S (~14 KT, 25 KM/H, 16 MPH or 1,400 FPM) | ||
| Environmental Sealing | Electronics enclosure IP67 – water resistant to 1 m. (3 ft.) | ||
| Shock Resistance | Drop tested to 2 m. (6 ft.) | ||
| Auto Shutdown | 45 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 | ||
| Pressure Sensor | Monolithic Silicon Piezoreisitive sensor | ||
| Dimensions | Unit: 122 x 42 x 20 mm (4.8 x 1.7 x 0.8 in.) Cover: 122 x 46 x 26 mm (4.6 x 1.8 x 1.1 in.) |
||
| Weight | Unit: 2.3oz (65gr) Cover: 1.3oz (37gr) |
||
| 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) | ||
| Temperature Limitations | The Kestrel temperature sensor is able to measure temperatures as low as -30C (-22F) and as high as 70C (158F). 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. 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. | ||
| Patents | 5,783,753; 5,939,645; Other patents pending. | ||
