| 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. |
