VelociCalc® Air Velocity Meters

VelociCalc air velocity meters are ideal tools for measuring face velocity measurements in fume hoods and spray booths or for IAQ and ventilation system checks.

The Models 9515 is an economical choices for Air Velocity Meters without compromising accuracy or precision. The Model 9515 features a 40-inch (101.6 cm) telescoping integrated probe for difficult to reach measurements.

The Models 9535 and 9545 thermal anemometers are like having multiple instruments 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, and 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.
