The TSI Alnor VelociCalc 9545 air velocity meter simultaneously measures and data logs air velocity, temperature and relative humidity using a single probe with multiple sensors. Typically used to measure HVAC system performance, critical environment certifications and duct traverses, the 9545 can also calculate volumetric flow and the actual/standard velocity.

TSI Alnor air velocity meters measure across a range of 0 to 6,000 ft/min (0 to 30 m/s) with an accuracy of ±3% of reading or ±3 ft/min (±0.015 m/s). Temperature is measured from 0 to 200°F (-18 to 93°C) with an accuracy of ±0.5°F (±0.3°C) and relative humidity is measured from 0 to 95% RH with ±3% RH accuracy.The range of volumetric flow rates is a function of velocity and duct size. The TSI Alnor VelociCalc 9545 displays up to three measurements simultaneously. Additionally, the VelociCalc meter is capable of logging 12,700+ samples and 100 test IDs which can be easily downloaded to a computer with the LogDat2 software that comes standard with the meter.

The VelociCalc 9545 model features a 40" telescoping straight probe, while the 9545-A model has a telescoping articulated probe.
