For Dehumidification, HVAC & Home Inspection Professionals
Calculate CFM without a calculator!
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:
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.
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.
