Dwyer VT-200 Vane Thermo Anemometer, the ideal device for balancing air and heating systems or for testing for fans and blowers operations. This is able to calculate air volume per minute in cubic feet and cubic meters per minute. This helps you to calculate airspeeds with ±3 percent accuracy in ft/min, m / s, knots, km / h, and mph. Wind speed and temperature in select units or in airflow and air-surface can be viewed with the revolutionary multifunctional LCD. Equipped with an integrated data logger to store a thousand measurements. Could be also used to transfer data to PC using the RS-232 communication.

Features of Dwyer VT-200 Vane Thermo Anemometer :

  •  Verify fume hood flow performance
  • Measures Air Volume/Velocity/Temperatur
  • Check diffuser of register face velocities
