TSI's VelociCalc Air Velocity Meters are easy to use from the first time you pick them up. The meters measure velocity and temperature, and with a few simple keystrokes the calculate flowrate, perform multi-value averaging, and determine minimum and maximum readings.
The VelociCalc Features
- Extended velocity range of 0 to 30 m/s
- Temperature range of -17.8 to 93.3°C
- Easy-to-read digital display
- Variable time constant modes available for a steady display when measuring fluctuating flows
- 94.0 cm telescoping probe with etched length marks to make duct traverse measurements easier
- Sampling function allows for easy recording of multiple measuring points
- Statistics function can display average, maximum and minimum values, and the number of recorded samples
- Flowrate feature allows for simple and quick calculations of volumetric flowrate when the user inputs the duct shape and size
- Optional portable printer provides a hard copy documentation of your readings
- Includes a battery check that monitors battery level to ensure accurate readings
- NIST*-traceable calibration certificate
MODEL OPTIONS
The Models 8345 and 8346 both measure air velocity, temperature, calculate flowrate, perform multi-value averaging, and determine minimum and maximum readings. The Model 8346 has the added feature of an articulating probe for measurements in ceiling outlet flows or clean benches.
APPLICATIONS
- HVAC duct measurements
- Fume hood face velocity tests
- Clean room studies
- Wind tunnel work
- Filter face velocity measurements
- Indoor Air Quality tests

1 Temperature compensated over an air temperature range of 5 to 65°C (40 to 150°F).
2 The accuracy statement of 3.0% of reading or ±3 ft (±0.15 m/s), applies to 30 ft/min through 6,000 ft/min.
3 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. Add uncertainty of 0.5°C (0.9°F) for exposure to RF radiation levels of 3 V/m per IEC 801-3.
4 Actual range is a function of maximum velocity and duct size.
