These dependable meters measure air velocity and temperature, calculate flow rate and perform statistical calculations. Models are available that add a humidity measurement and perform dew point and wet bulb temperature calculations.

Professionals have found VelociCalc air velocity meters to be ideal tools for measuring face velocity measurements in fume hoods and spray booths, or for IAQ and ventilation system checks.

The Models 9515 and 9525 are 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 Model 9525 has a 3-inch retractable probe, plus is UL listed as intrinsically safe for use in hazardous locations for Division 1 and 2 in Class I, Groups C and D; Class II, Groups E F and G; and Class III.

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.
