VELOCICALC®
AIR VELOCITY METERS
MODELS 9515, 9535,
9535-A, 9545 AND 9545-A
The dependable TSI VelociCalc® Air Velocity Meters measure air velocity
and temperature. Models are available to calculate ow rate, perform
statistical calculations, and measure humidity with dew point and wet
bulb temperature conversions.
The Model 9515 is an economical choice for a digital air velocity
meter, without compromising accuracy or precision. Professionals
nd them to be the ideal tool for face velocity measurements in
fume hoods, spray booths, or ventilation system checks.
The Models 9535 and 9545 Air Velocity Meters simultaneously
measure and data log several ventilation parameters using a
single probe with multiple sensors. Both models measure velocity,
temperature and calculate ow.
The Model 9545 also measures relative humidity, and calculates
dew point and wet bulb temperature.

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 4000 ft/min. (0.15 m/s through
20 m/s) for the Model 9515, and 30 ft/min through 6,000 ft/min (0.15 m/s through
30 m/s) for Models 9535 and 9545.
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.
