VelociCalc® Air
Velocity Meters
Professionals
have found VelociCalc air velocity meters to
be ideal tools for 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. | Features

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. Includes 1%
hysteresis. Specifications are subject to change without notice. |
