Kestrel 4400 (0844) Heat Stress Tracker in Orange Overview

Kestrel Heat Stress Trackers
The Kestrel Heat Stress Trackers provide waterless WBGT measurement. Until now, most accurate WBGT measurement tools were large, cumbersome to use (requiring the transport of distilled water along with the measurement unit) and/or expensive. The Kestrel Heat Stress Tracker is the most user-friendly WBGT meter on the market:

Features:

  • Quick setup. No time-consuming setup required. Get accurate readings within minutes.
  • User-settable warning zones. Set WBGT warning zone temperature ranges in accordance with state or school heat acclimatization regulations or OSHA-specific recommended guidelines.
  • Data-logging. Store up to 2300 data points in its memory (model dependent), record information to refer back to.
  • Easy-to-use. Easily navigate through the screens to quickly access the appropriate information.
  • Capture information on the spot. Capture information on hand without having the recording feature set up in advance.
  • Drop-proof. The Kestrel undergoes a Procedure IV Transit Shock test, which consists of 20 drops from 5 ft., making it extremely durable and rugged.
  • Light-weight and portable. Handheld, weighing in at 4.5 ounces, the unit is portable and can easily fit into a pocket,gym bag or tool box.
  • Cost to own is less expensive than renting. Save money by buying in the short and long term.
  • Tripod-mountable. Conveniently record data with tripod mountable option.
  • Waterproof. The Heat Stress Tracker is IP-67 sealed to exclude dust and water at 3 ft.
The Kestrel 4400 Heat Stress Tracker provides waterless WBGT measurement. Until now, most accurate WBGT measurement tools were large, cumbersome to use (requiring the transport of distilled water along with the measurement unit) and/or expensive. Kestrel added a compact black globe thermometer to the already proven sensor suite of the Kestrel 4000 Weather & Environmental Meters, then built in advanced algorithms to calculate WBGT values within 2.18 deg C of the values obtained from a full-sized WBGT setup. WBGT is quickly replacing heat stress index as the standard for detecting heat stress illness. Both the NFL and FIFA have adopted WBGT as their methods of accessing risk of playing and practicing. As a matter of fact, every NFL team has at least two Kestrel 4400 Heat Stress Trackers! The Kestrel 4400 is recommended by the Kory Stringer Institute as the Meter of choice for WBGT measuring. You can find the Kestrel 4400 in many High Schools, Colleges, Universities and Professional Sports teams throughout the world. The Kestrel 4400 is also a popular choice for our Military customers as well. Click here to read more about the Korey Stringer Institute.
