VelociCalc Multi-Function Ventilation Meter 9565-P TSI

VelociCalc Multi-Function Ventilation Meter 9565-P TSI

Precision Pressure and Airflow Diagnostics for HVAC and IAQ Professionals

The VelociCalc® 9565-P TSI is a portable, handheld multi-function ventilation meter designed for professionals who require precise pressure measurements and comprehensive HVAC diagnostics. Equipped with a differential and barometric pressure sensor, and inputs for two K-type thermocouples, the VelociCalc Multi-Function Ventilation Meter 9565-P TSI enables detailed testing of air handling systems, cleanrooms, fume hoods, and ventilation performance.

This model does not include a velocity or IAQ probe, making it ideal for users who focus on pressure-based assessments and thermal diagnostics. With an intuitive menu-driven interface, on-screen prompts, and large graphical display, users can quickly configure settings, log data, and analyze results in the field or laboratory.

Its rugged, over-molded housing, Bluetooth connectivity, and flexible data logging options make it a powerful tool for commissioning, balancing, and troubleshooting HVAC and IAQ systems.
