Description Specifications Literature Video Accessories Description 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. 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 probe Model 964 or 966, and grid guided duct traverse methodologies. Applications HVAC testing and balancing Clean room testing Biological safety cabinet and laboratory fume hood testing HVAC commissioning and troubleshooting IAQ investigations Ventilation effectiveness with percent outside air calculation Features & Benefits Large, high-resolution color display Intuitive menu structure allows for ease of use and setup Optional smart plug-in probes, including thermoanemometer, rotating vane and CO2 probes with calibration certificates Input for K-alloy thermocouple User-customizable soft keys for quick access to common functions Calculate the percentage of outdoor air with IAQ probe Integrated magnets for hands-free operation Supports multiple languages Air density compensation with on board barometric pressure sensor and temperature input Static and differential pressure measurement Pitot probe duct traverse Programmable K-factors Print data from instrument with optional USB portable printer (802241) Print data from instrument with optional bluetooth wireless portable printer (802241) Model 9650 only Step by step guided workflows: Heat flow calculations in BTU/hr or kW Percentage of outdoor air Duct traverse grid measurements for: ASHRAE 111 log-Tchebycheff ASHRAE 111 equal area EN 12599 EN 16211 State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
