Blaze Orange

The Kestrel 5400 Heat Stress Meter is the most user-friendly WBGT meter on the market - revolutionary in size, cost and capability for measuring heat stress.It provides on-screen alarms when conditions enter the caution and danger zones, providing clear and immediate guidance that heat illness prevention steps must be taken.

The 5400 is packed with 15 separate environmental measurements including wet bulb globe temperature (WBGT, a calculation of the heat stress in direct sunlight), heat index (a calculation of the heat stress in shade), and thermal work limit (TWL, another recognized composite heat stress prediction tool).

It also measures air/water temperature, humidity, altitude, barometric pressure and more. Engineered for performance, the rugged 5400 is fully waterproof and features a large, backlit screen for easy viewing in bright sun or darkness.

The 5400 tracks and logs thousands of time-stamped data points, which you can easily transfer to any PC via USB (cable sold separately).

The Vane Mount allows you to set up the 5400 for portable, hands-free monitoring. The design and function of the Kestrel 5400 make it an indispensable tool for many applications including athletics, construction, HVAC, military, HAZMAT, industrial hygiene and facilities management. Amateur and pro athlete deaths from heat exposure are on the rise.

Military and K9 units struggle to keep soldiers healthy while preparing them for gruelling heat. OSHA is campaigning to prevent heat illness and deaths in outdoor workers. In every instance, accurate and localized measurement of heat stress conditions is a key component of a heat illness prevention plan. The Kestrel 5400 Heat Stress Tracker answers this need.

Runs on one AA battery - included. The Kestrel 5400 is proudly designed and manufactured in the USA, and is backed by a 5-year warranty..
