and 9545-A
Model 9545
Features and Benefits
Accurate air velocity measurement
Easy to read display
Simple to operate
Calibration certificate included
Models 9535, 9535-A, 9545 and 9545-A
Simultaneously measure temperature and velocity
Displays up to three measurements simultaneously
Calculates volumetric flow and actual/standard velocity
Data log 12,700+ samples and 100 test IDs
LogDat2TM downloading software included
Articulated probe versions available (9535-A and 9545-A)
Measures humidity (Model 9545 and 9545-A)
The Model 9515 is an economical choice for a digital air
velocity meter, without compromising accuracy or precision.
Professionals find 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 flow.
The Model 9545 also measures relative humidity, and
calculates dew point and wet bulb temperature.
Applications
HVAC system performance
Commissioning
Plant maintenance
Critical environment certification
Duct traverses

Temperature compensated over an air temperature range of 5 to 65°C (40 to 150°F).
The accuracy statement begins at 0.15 m/s through 20 m/s (30 ft/min through 4000 ft/min.) for the Model 9515, and
0.15 m/s through 30 m/s (30 ft/min through 6,000 ft/min) for Models 9535 and 9545.
Accuracy with instrument case at 25°C (77°F), add uncertainty of 0.03°C/°C (0.05°F/°F) for change in
instrument temperature.
Accuracy with probe at 25°C (77°F). Add uncertainty of 0.2% RH/°C (0.1% RH/°F) for change in probe temperature.
