||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.
||Recommended -20ºC to
80ºC (-4ºF to 176ºF)
||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.
Other patents pending.
||Wind speed and temperature
measurements are tested at the factory before packaging. Factory certification
is available for additional fee.
Product is CE certified.
||Standard 2-year warranty
covers parts and labor.
