Firefighters train to withstand the challenge of heavy exertion in extreme conditions. Excessive heat is a constant companion, and protective clothing and equipment increases the physical strain. Heat acclimatisation through training is a key aspect but doing so without incurring heat illness or injury is equally critical and challenging, using Wet Bulb Globe Temperature (WBGT) measurements and introducing work, rest and hydration guidelines is an essential element.
Using WBGT is a more effective measure of heat stress for the firefighter because it includes the effects of radiant heat from the sun, fire, or hot surfaces. The Kestrel Fire Weather Meter PRO WBGT monitors WBGT and fire weather during training and operations. With pre-programmed ACGIH guidelines and alert settings to indicate when conditions have become extremely unsafe, the Kestrel Fire Weather Meter PRO with WBGT is the ultimate tool for increasing the safety of your crew.
The Kestrel 5400FW also calculates and logs over 10,000 sets of time-stamped data.
The Kestrel 5400FW has Bluetooth connectivity allowing you to transfer data wirelessly to an iOS (iPhone, iPad) device or Android smartphone or tablet when within range using the appropriate Kestrel LiNK App. You can also transfer data wirelessly to a Windows or Mac computer using the optional Kestrel Bluetooth USB Dongle (sold separately). Data can be viewed live on the App up to 100 feet away (line of sight).
When combined with the Kestrel Vane Mount and Kestrel Tripod the Kestrel 5400FW becomes a stand-alone environmental monitoring station as the large wind vane and precision pivot keep the Kestrel oriented into the wind for continuous measurement and logging of all the key environmental parameters including wind speed, direction, temperature, humidity, pressure, dew point, elevation, density altitude, PIG, FDFM and more at the exact location required.
Mil-SPEC-810G drop tested with an IP67 waterproof rating the Kestrel 5400FW is designed and constructed to withstand the harsh treatment it will receive in the agricultural industry. The unit comes with a five-year warranty and certificate of conformity as standard.
