| 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

| 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. |
| Warranty |
Standard 2-year warranty covers
parts and labor. |
