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