The Nielsen Kellerman Kestrel 4200 Pocket 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 Nielsen Kellerman Kestrel 4200 Pocket Air Flow Tracker can truly be personalized for every technician. Easy set-up screens allow the Kestrel 4200 to display only relevant readings, and hide screens not related to the job. Plus the Kestrel 4200 user screens group pertinent information on one easily referenced screen.

The Kestrel 4200 Pocket Air Flow Tracker 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.

Every Nielsen Kellerman Kestrel 4200 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 Kestrel 4200’s hold and averaging functions, and it’s the only instrument HVAC technicians need to perform a variety of jobs.

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 Pocket Air Flow Tracker 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.

• Volume air flow in cfm, L/s. m3/s, m3/m, m3/h
• Wind Speed (current, average, maximum)
• Heat Stress Index
• Temperature of air, water, snow in degrees F or C
• Relative humidity in %
• Dewpoint
• Barometric pressure
• Altitude
• Density altitude
• Wet bulb temperature
• Windchill
• Humidity ratio.

Both real-time and logged data can be transferred wirelessly and automatically to a laptop or PDA, making the Kestrel 4200 Pocket Air Flow Tracker with Bluetooth the perfect tool for virtually any job that requires quick and reliable weather data. The Bluetooth version of the Kestrel 4200 includes custom communication software designed to quickly and easily configure your data transmission frequency, download logged data, graph data, and transfer data to other applications. Data transmission range adjustment allows you to maximize power to communicate with your Kestrel 4200 Pocket Air Flow Tracker at up to a 30 feet range, or reduce power for closer, more secure operation. Individual unit ID’s ensure you pair with the Kestrel 4200 you want, even when more than one system is operating in the same area. And, permanently coded unique 4-digit Pin numbers provide extra security when pairing and transmitting data.
