Kestrel 0842B Kestrel 4200 Pocket Air Flow Tracker with Bluetooth at $349.00 with FREE shipping, makes HVAC technician’s 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.
Now, with integrated Bluetooth technology, both real-time and logged data can be transferred wirelessly and automatically to a laptop or PDA. Every Bluetooth Kestrel will include custom communication software designed to quickly and easily configure your data transmission frequency, download logged data, graph data, and transfer data to other applications.
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.
