The Kestrel 4100 Pocket Air Flow Meter was engineered specifically
with the HVAC technician's many needs in mind. In addition to measuring
volume air flow, this multi-functional precision instrument also
measures temperature, relative humidity and dewpoint, either ambient or
in any accessible airflow. Tired of cumbersome equations to calculate the CFM? The 4100 makes
it possible to determine CFM without using a calculator. For immediate
and accurate air flow readings, simply enter the duct shape and
dimensions, hold the 4100 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. 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. Don't let the inexpensive price tag fool you — the Kestrel 4100 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. This all-in-one instrument is so comprehensive, accurate and
innovative that it won the ACHR News Dealer Design Award for excellence
in product design. "Every technician I employ will have one of these
units ASAP!" said one of the Dealer Design judges. The Kestrel 4100 Air Flow Meter is an affordable tool that is easy
to carry and use, and is ideal for facilities managers, HVAC equipment
sales people, home inspectors, dehumidification specialists, field
installers and technicians. Kestrel 4100 Measures
