The LH866A thermal anemometer is an instrument that uses a thin metal wire placed in a flow field to measure velocity by heating current. The temperature of the metal wire remains constant through heating current, so when the wind speed changes, the heat transfer of the metal wire changes accordingly, resulting in a change in electrical signal that can determine the actual velocity of the flow field. Due to its high-frequency response, LH866A thermal anemometer is an early and widely used single point measuring instrument in turbulence and flow research.
