Multifunction measuring device VelociCalc 9650

air velocitydigitalHVAC

The VelociCalc® Meter Model 9650 is used to measure HVAC system pressures and can be connected to pitot probes for performing duct traverses. It’s ergonomic design includes a probe holder and integrated magnets allowing for attachment to exposed ductwork or other metallic surfaces for hands-free operation. It's 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 % of outside air when used with an IAQ probe, heat flow calculations for testing heating and cooling coils when used with additional probes and grid guided duct traverse methodologies. Applications: - HVAC testing & balancing - Clean room testing - Biological safety cabinet and laboratory fume hood testing - HVAC commissioning and troubleshooting - IAQ investigations - Ventilation effectiveness with % outside air calculation Features & Benefits: - Large, high-res color display - Intuitive menu structure - Optional smart plug-in probes incl. thermoanemometer, rotating vane and CO2 probes with calibration certificates - Input for K-alloy thermocouple - User-customizable soft keys - Calculate the % of outdoor air with IAQ probe - Integrated magnets - Multiple languages - Air density compensation with on board barometric pressure sensor and temperature input - Static & differential pressure measurement - Pitot probe duct traverse - Programmable K-factors - Print data with optional portable printers - Step by step guided workflows: Heat flow calculations in BTU/hr or kW, % of outdoor air - Duct traverse grid measurements for: ASHRAE 111 log-Tchebycheff, ASHRAE 111 equal area, EN 12599, EN 16211
