Kestrel has taken the calculations and guess work out of air flow measurement with the Kestrel 4100 Air Flow Tracker. Simply enter the duct shape and dimensions, hold the Kestrel 4100 in the air flow and the volume air flow readings are instantaneously displayed... no calculator required! The Kestrel 4100 also measures temperature, relative humidity, and dew point, either ambient or in any accessible airflow.
This versatile instrument features a powerful data logger that records 480 sets of data at user-selectable time intervals (up to 34 weeks of data can be recorded!). You may review the logged data in clear on-screen graphs or upload the data to a PC for in-depth review and graphing. The Kestrel 4100 is an affordable tool that is easy to carry and use! Perfect for facilities managers and HVAC equipment sales people, field installers, and technicians.
