Kestrel 4200 Pocket Air Flow Tracker Overview


The Kestrel 4200 Pocket Air Flow Tracker has made HVAC technicians’ jobs even easier with built-in wet bulb temperature and humidity ratio readings. The Kestrel 4200 features automatic air flow readings- for immediate and accurate measurements. Simply enter the duct shape and dimensions, hold the 4200 in the air flow and the volume air flow readings are displayed…no calculator required! The convenient averaging mode ensures accurate CFM readings in any airflow or duct size and shape.Don’t let the affordable price tag fool you- the Kestrel 4200 is as accurate and comprehensive as instruments costing far more. On-screen customization allows each technician to personalize their unit. Easy set-up screens display only relevant readings, and hide screens not relative to the job. Plus the Kestrel’s User Screens group pertinent information on one easily referenced screen. Rounding out the features is a 1600 memory point data logger and PC interfacing capabilities.
