TSI 9600 series VelociCalc | Multi-function ventilation meter

The TSI VelociCalc and VelociCalc Pro multi-function ventilation meters are portable, handheld, ventilation test instruments featuring a full colour menu-driven display for easy operation.  Available in three versions with a range of smart plug-in probes that includes devices for air velocity and indoor air quality (IAQ).

Features of this instrument range include a built-in workflow for calculating the percentage of outside air used to determine ventilation effectiveness in a building or room. The VelociCalc Pro adds additional built-in workflows for heat flow calculation plus four methodologies for performing a duct traverse which speeds up the measurement process while reducing errors.
