TSI 9545 VelociCalc Air Velocity Meter Series

The TSI VelociCalc 9545 Series is a handheld air velocity meter designed for measuring air velocity, temperature, and humidity in HVAC systems and indoor environments. ATEC offers models 9545 and 9545A offering multiple features for various applications.

The TSI 9545 measures air velocity from 0 to 6000 ft/min (0 to 30 m/s), temperature from 14°F to 140°F (-10°C to 60°C), and logs up to 12,700 samples. It includes a telescoping probe with an articulating head for easy access to hard-to-reach areas. The TSI 9545A provides the same measurements with an articulated probe. Both models calculate dew point, wet bulb temperature, and volumetric flow and support LogDat2 software for efficient data management.
