Cobra (fast-response velocity) probe
System features:
The Hanghua FR series fast-response velocity probe is a velocity measuring instrument. This instrument is designed for velocity measurement by researchers in fields such as wind engineering, automotive, HVAC, energy and power , aviation, etc. It features a wide measurement range, high accuracy, velocity direction measurement, high-frequency response, and durability. The Hanghua FR series probes have two products. FR02 is designed to be comparable to the Australian Cobra probe, featuring a four-hole probe structure with a lower measurement range (2-40m/s) and reliable results at low speeds. On the other hand, FR03 features a five-hole probe structure with a wider measurement range and excellent high-speed performance, with better dynamic performance (frequency response of 5kHz). The specific performance indicators for both products are as follows:
