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 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.

Temperature compensated over an air temperature range of 40 to 150°F
(5 to 65°C).
2 The accuracy statement begins at 30 ft/min through 6,000 ft/min
(0.15 m/s through 30 m/s).
3 Accuracy with instrument case at 77°F (25°C), add uncertainty
of 0.05°F/°F (0.03°C/°C) for change in instrument
temperature.
4 Accuracy with probe at 77°F (25°C). Add uncertainty of
0.1% RH/°F (0.2% RH/°C) for change in probe temperature.
