Kestrel 4200 Measures
- Volume air flow in cfm, L/s, m³/s, m³/m, m³/h
- Air velocity (current, average, and maximum)
- Heat stress index
- Windchill
- Relative humidity
- Dewpoint
- Temperature in °F or °C
- Humidity ratio
- Barometric pressure
- Wet bulb temperature
- Altitude
- Density altitude
Tired of cumbersome equations to calculate CFM?
Like the 4100, 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:
- Enter the duct shape and dimensions.
- Hold the 4200 in the air flow.
- Volume air flow readings are displayed... no calculator
required!
Innovative Design and Features
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.
Easy-to-Use Data Logging & Computer Upload
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 related 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 4200’s hold and
averaging functions, and it’s the only instrument HVAC technicians
need to perform a variety of jobs.
