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. Certification Wind speed, temperature and humidity measurements are tested at the factory before packaging. Factory certification is available for additional fee. Product is CE certified.
