The Kestrel 5400 Heat Stress Tracker is a trusted and accurate handheld, portable, WBGT (Wet Bulb Globe Temperature) measurement tool and environmental data logger.  No need for distilled water, bulky globes, complicated setup or expensive equipment.  Getting accurate measurements couldn’t be easier: just hold the Kestrel 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. The Kestrel 5400 even comes preprogrammed with several athletics, industrial, and military guidelines to further ease the set-up process.

Unlike other WBGT meters on the market the KEstrel 5400 Heat Stress Tracker measures wind speed, maximum wind gusts, temperature, humidity, pressure, wind chill, density altitude and more. No matter what your activity, the Kestrel 5400 provides insight into the critical conditions affecting safety, performance and success. The Kestrel 5400 with LiNK wireless data communication adds a compass for tracking wind direction as well, expanding its usability to include HAZMAT response, and even measuring headwind at the running track!
