The TSI Alnor VelociCalc 9565 Series multi-function ventilation meters are portable, handheld instruments available with or without a differential pressure sensor. Generally used for a wide array of applications-- HVAC, clean room certification, ventilation evaluations, thermal comfort studes, IAQ investigations and process air flow testing-- the TSI Alnor VelociCalc is designed to work with a wide range of plug-in probes.
With probes designed to measure air velocity, temperature, humidity, CO and CO2, the TSI Alnor VelociCalc 9565 Series multi-function meters can calculate air flow, heat flow, turbulence, wet bulb and dew point temperature. The TSI Alnor VelociCalc 9565 Series features a large graphic display which can simultaneously display up to 5 measurements. Up to 26,500+ samples and 100 test IDs can be logged, either manually or continuously, into the internal memory. Other features of the TSI Alnor VelociCalc 9565 Series multi-function meters include TrakPro and LogDat2 software and the ability to name test IDs.
TrakPro data analysis software is a Windows-based software program that works with a variety of TSI data logging instruments, including the TSI Alnor VelociCalc 9565 Series. This unique software helps you pre-program instruments, store and organize your test data, and generate detailed graphs and reports needed to effectively communicate results. The LogDat2 software transfers stored data to a computer spreadsheet program. It is necessary for downloading data from the TSI Alnor VelociCalc meters.

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.
