Kestrel 4200 Pocket Air Flow Tracker

The Kestrel 4200 has made 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.

Tired of cumbersome equations to calculate the CFM? Like the 4100, the Kestrel 4200 has taken the calculations and guess-work out of air flow measurements with automatic air flow readings. For immediate and accurate air flow readings, 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.

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 customization, the 4200 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 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.
The Kestrel 4200 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.
