The VelociCalc® Model 9565 series are portable, handheld, Multi-Function
Ventilation Test Instruments featuring a menu-driven user interface for
easy operation in your local language. On-screen prompts and step-by-step
instructions guide the user through instrument setup, operation, and eld
calibration. The 9565 also features an ergonomic, overmolded case design with
probe holder and a keypad lockout to prevent tampering during unattended use.
These instruments are available with or without a dierential pressure sensor
and are designed to work with a wide range of plug-in probes.

1
Pressure velocity measurements are not recommended below 1,000 ft/min (5 m/s) and
are best suited to velocities over 2,000 ft/min (10.00 m/s). Range can vary depending on
barometric pressure.
2
Accuracy is a function of converting pressure to velocity. Conversion accuracy improves
when actual pressure values increase.
3
Overpressure range = 190 in. H2O, 48 kPa (360 mmHg).
4
Temperature compensated over an air temperature range of 40 to 150°F (5 to 65°C).
5
The accuracy statement begins at 30 ft/min through 9,999 ft/min (0.15 m/s through 50 m/s).
6
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.
7
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.
8
At 77°F (25°C). Add uncertainty of ±0.2%/°F (0.36%/°C) for change in temperature.
9
At calibration temperature. Add uncertainty of ±0.28%/°F (0.5%/°C) for change
in temperature.
10
When response factor is set to 1.00.
