From the Nielsen Kellerman Kestrel 3000’s accurate relative humidity readings, the device also calculates the dewpoint and heat stress index—important information to know when working or playing outdoors in hot and humid conditions.

Nielsen Kellerman was the first to provide accurate relative humidity measurements from a hand-held weather meter, and the Kestrel 3000 Pocket Weather Meter features two patents on its humidity measuring sensors. A testament to the Kestrel 3000’s accuracy: it’s become practically required equipment for wildland firefighters—users whose lives literally depend on the accurate weather data their Nielsen Kellerman Kestrel 3000 Pocket Weather Meter provides.

Kestrel Wind Meters are used by NFL trainers to determine how frequently the athletes need to hydrate, and when the conditions are unhealthy for strenuous exercise.
