The Kestrel 5400 Heat Stress Tracker is a uniquely powerful measuring and data logging compact instrument. The heat stress tracker is a trusted and accurate handheld, portable, Wet Bulb Globe Temperature (WBGT) measurement tool. No need for distilled water, bulky globes, complicated setup or expensive equipment. Hold the heat stress tracker in the area of interest for both instantaneous and average WBGT measurements. Set the appropriate WBGT thresholds for flag warnings and the loud buzzer, bright LED beacon and on-screen warnings provide instant notification of dangerous conditions. Providing insight into the critical conditions affecting safety, performance and success. The Kestrel 5400 even comes pre-programmed with several athletics, industrial, and military guidelines for easy set-up.

The Kestrel 5400 provides trusted accuracy, reliability for measuring other weather data such as; wind speed, maximum wind gusts, temperature, humidity, pressure, wind chill, density altitude and more. The digital compass enables tracking for wind direction and headwind, expanding its usability to include HAZMAT response.

When paired with the included rotating vane mount and a tripod (sold separately) the meter becomes an independent monitoring station. The rotating vane securely mounts the Kestrel 5400 to any tripod or other -20 fitted bracket. The large wind vane and precision pivot keeps the meter oriented into the wind for continuous measurement and logging of wind speed and all other key weather variables. Use it for research, safety, athletics & outdoor sports, construction & HVAC, facility management, firefighting, HAZMAT applications, miltary operations or other activities that require accurate monitoring. The meter features a large, high-resolution and contrast display along with a dual color backlight. It is drop-proof, dust-proof, waterproof and able to withstand harsh environments without damage. The Kestrel 5400 monitors and logs over 10,000 weather data sets that are time-stamped.

All Kestrel 5 Series meters allow a wired communication between the meter and a PC or Mac. Use the USB Data Transfer Cable (sold separately) and Kestrel LiNK free software to install firmware updates and upload data logged from your Kestrel meter in a comma delimited text file format. Save/View in a spreadsheet, database or text-editor software program. Communication between the USB cable and Kestrel meter is optical. Therefore does not jeopardize the Kestrel's watertight seal.

With the Kestrel LiNK free App, you can wirelessly connect any LiNK-enabled meter via Bluetooth to an iPhone, iPad or Android mobile device.
