Kestrel 5500 Environmental Meter, Olive Drab

DESCRIPTION

The Kestrel 5500 does it all – measures altitude, barometric pressure, crosswind, density altitude, dew point temperature, direction (wind direction and orientation), headwind/tailwind, heat stress index, relative humidity, station pressure (absolute pressure), temperature, wet bulb temperature (Psychrometric), wind chill, and wind speed. The Kestrel 5500 features a large, high contrast screen, dual color backlight, scratch- and breakage-resistant window, corrosion-resistant battery compartment with secure door, intuitive user-interface, plus it tracks and logs over 10,000 sets of time-stamped data. Data can be transferred to a PC/MAC with the optional waterproof USB Data Transfer Cable (sold separately). Combine the Kestrel 5500 with a portable vane mount and portable tripod (each sold separately) for a data-logging weather station that rotates in even the slightest breeze and is ideal for short-term monitoring. This versatile, waterproof instrument floats, features an easy-to-read backlit display, and has an auto shutdown feature which activates after 15 minutes without a button press (feature can be disabled). Lanyard, protective pouch, lithium AA battery (average life 400 hours), certificate of conformity, and instruction manual are included. Five-year manufacturers warranty.
