Kestrel 5400 Heat Stress Tracker

The Kestrel 5400 provides 15 measurements in all including altitude, barometric pressure, density altitude, dew point temperature, globe temperature, heat stress index, naturally aspirated wet bulb temperature, relative humidity, station pressure (absolute pressure), temperature, thermal work limit (TWL), wet bulb temperature (Psychrometric), wet bulb globe temperature (WBGT), wind chill, and wind speed. The Kestrel 5400 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 log can be transferred to a mobile device wirelessly, or to a PC/MAC with the optional waterproof USB Data Transfer Cable (sold separately). Combine the Kestrel 5400 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 manufacturer’s warranty.
