Heat-resistant anemometers have been developed for measuring horizontal and vertical air flow in fire behavior studies. The anemometers will continue to produce data as long as the anemometer body is less than 650ºF. They can survive brief immersion in flame without major damage. These air-flow sensors have aluminum bodies and rotor hubs and stainless steel cups or vanes supported by stainless steel tubing. The anemometers are suitable for use in normal situations as well as in high temperatures.
