The VelociCalc Meter Model 9650 is used to measure HVAC system pressures and can be connected to pitot probes for performing duct traverses. Its ergonomic design includes a probe holder and integrated magnets allowing for attachment to exposed ductwork or other metallic surfaces for hands-free operation.
The Model 9650 is designed to work with a wide range of plug-in probes for measuring air velocities or IAQ parameters. In addition, the 9650 includes built-in workflows for calculating the percentage of outside air when used with an IAQ probe, heat flow calculations for testing heating and cooling coils when used with specific probe types, and grid guided duct traverse methodologies.
3 Year Warranty for the meter only (2 Year Manufacturer Warranty + Bonus 1 Year Instrument Choice Warranty)
