TSI 9535 VelociCalc Air Velocity Meter
The TSI Alnor VelociCalc 9535 air velocity meter simultaneously measures and data logs air velocity and temperature using a single probe with multiple sensors. Typically used to measure HVAC system performance as well as critical environment certifications and duct traverses, the 9535 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). The range of volumetric flow rates is a function of velocity and duct size. The TSI Alnor VelociCalc 9535 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 9535 model features a telescoping straight probe, while the 9535-A model has a telescoping articulated probe.
