Rental Air Velocity & Indoor Air Quality (IAQ) Meters

Air velocity meters measure velocity, temperature and calculate flow. Data logging and other measurements can be added.

Professionals find them the ideal tool for face velocity measurements in fume hoods, spray booths, or for IAQ and ventilation system checks.

TSI VelociCalc® Models 9535 and 9545

VelociCalc Model 9545
VelociCalc Model 9545

The Models 9535 and 9545 air velocity meters are like having multiple meters — for the price of just one. These meters simultaneously measure and data log several ventilation parameters using a single probe with multiple sensors. Both models measure velocity, temperature and calculate flow. The Model 9545 also measures relative humidity, calculates dew point and wet bulb temperature. Models 9535 and 9545 have telescopic straight probes; Models 9535-A and 9545-A have telescopic articulated probes.
