TSI 5725 | Vane anemometer

Contact Instrument Solutions


The TSI 5725 Velocicalc rotating vane anemometer is a high performance, yet simple to use, instrument for the measurement of air velocity and volume. It can also calculates flow rate, performs averaging, and can determine minimum and maximum readings. Using sweep mode you can quickly provide one averaged reading of velocity or volume over a large measurement area. The large vane head automatically averages velocity and volume readings.


  • Reversible 100 mm head to read supply and return (exhaust) flows
  • Calculates volumetric flow rate when user inputs duct shape and size, or area
  • Sampling function records multiple point measurements
  • Automatic averaging of air velocity
  • Simultaneously displays velocity and temperature
  • Sweep mode for one overall measurement
  • Optional telescopic handle available
  • Compatible with optional Aircone flow hoods
  • Logs 12,700+ samples with a time and date stamp
  • Recall, review, store data
