Most user-friendly WBGT meter on the market. Detect when heat-related conditions are unsafe well before your body does.
The Kestrel 5400 provides the same trusted accuracy, reliability, and usability as the original Kestrel 4400 and 4600. The Kestrel 5400 is a 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.
