VelociCalc Multi-Function Ventilation Meter 9650-NB-966 TSI

VelociCalc Multi-Function Ventilation Meter 9650-NB-966 TSI

Advanced Micromanometer with Articulated Probe (Non-Bluetooth Version)

The VelociCalc® 9650-NB-966 TSI is a portable, high-precision multi-function micromanometer designed for HVAC professionals who need reliable and accurate airflow diagnostics without wireless functionality. VelociCalc Multi-Function Ventilation Meter 9650-NB-966 TSI model combines the powerful 9650-NB meter with the 966 articulated probe, offering enhanced flexibility for reaching difficult measurement points in ducts and ventilation systems.

Engineered for airflow, pressure, temperature, and humidity measurements, the 9650-NB-966 is ideal for detailed ventilation assessments in critical environments such as cleanrooms, laboratories, and secure facilities where Bluetooth transmission is restricted.

Its user-friendly color interface, guided workflows, and advanced data logging capabilities make it a complete solution for HVAC commissioning, duct traverses, and IAQ analysis.
