Tired of cumbersome equations to calculate CFM?
Like the 4200, the Kestrel 4100 has taken the calculations and guess-work out of air flow measurements with automatic air flow readings. The convenient averaging mode ensures accurate CFM readings in any airflow or duct size and shape. For immediate and accurate air flow readings, simply:
- Enter the duct shape and dimensions.
- Hold the 4200 in the air flow.
- Volume air flow readings are displayed... no calculator required!
Easy-to-Use Data Logging & Computer Upload
The Kestrel 4100 air flow meter features a powerful data logger that records 2000 sets of measurements at user-selectable time intervals (over 2 years of data can be recorded). Logged data can be reviewed with the 4100’s on-screen graphing capabilities, or uploaded to a PC for in-depth review. The optional Kestrel Interface and accompanying Kestrel Communicator software makes long-term storage, in-depth analysis and detailed charting of stored data a breeze.
With on-screen customization, the 4100 can truly be personalized for every technician. Easy set-up screens allow the unit to 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.
NIST-Traceable Accuracy
Don’t let the inexpensive price tag fool you — the Kestrel 4200 is as accurate as instruments costing far more. Every Kestrel is individually calibrated to NIST-traceable standards and comes with a free Certificate of Conformity. (Individual NIST certificates and recalibration are also available.) Consider the 4100’s hold and averaging functions, and it’s the only instrument HVAC technicians need to perform a variety of jobs.
