Kestrel 4200 Pocket Air Flow Tracker

Kestrel 4200 Pocket Air Flow Tracker

Parameters Measured

Volume air flow (CFM), Current wind speed, average wind speed, maximum wind gust, temperature, wind chill, relative humidity, heat stress index, dewpoint temperature, wet bulb temperature, humidity ratio (grains), barometric pressure, altitude, density altitude.

The Kestrel 4200 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:

 1. Enter the duct shape and dimensions.
 2. Hold the 4200 in the air flow.
 3. Volume air flow readings are displayed... no calculator required!

The Kestrel 4200 makes HVAC technicians jobs even easier with automatic wet bulb temperature and humidity ratio readings. Of particular interest to dehumidification professionals, the Kestrel 4200 measures relative humidity, dewpoint, wet bulb temperature and heat stress index as well as the humidity ratio—and the patented dual chamber humidity sensor assures fast and accurate readings in any environment. This multi-functional precision instrument also measures: volume air flow, air velocity, barometric pressure, altitude, wind chill, heat stress index, temperature, relative humidity and dewpoint, either ambient or in any accessible airflow.

The Kestrel 4200 air flow meter features a powerful data logger that records 1600 sets of measurements at user-selectable time intervals (over 2 years of data can be recorded). Logged data can be reviewed with the 4200’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 customisation, the 4200 can truly be personalised for every technician. Easy set-up screens allow the unit to display only relevant readings, and hide screens not related to the job. Plus the Kestrel’s user screens group pertinent information on one easily referenced screen.

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).

If your application demands regular calibration, simply pop in a new impeller and the Kestrel air velocity meter is restored to like-new factory calibration standards.
