The Kestrel 4200 Pocket Air Flow Tracker is a premium addition to the expanding line of Kestrel pocket weather meters. The Kestrel 4200 monitors and reports an extensive list of environmental parameters — from temperature to barometric pressure, altitude, relative humidity, and more**. Like all Kestrel 4000-series meters, the Kestrel 4200 also stores that information and even charts up to 2000 data points for later analysis.

The Kestrel 4200 has all available monitoring functions of the Kestrel 4000, plus:

Humidity Ratio

Air flow

The 4200's vast range of environmental functions makes it useful for professionals of every sort, from firefighters to farmers – but the 4200's humidity and airflow monitoring functions provide particular value to HVAC and dehumidification experts. Simply enter the dimensions of a particular duct, hold your Kestrel 4200 near the opening, and it will calculate CFM for you.

The only Kestrel Meter with a longer list of available functions than the 4200 is the top-of-the-line Kestrel 4500 Pocket Weather Tracker. Equipped with a digital compass and capable of monitoring wind direction, crosswind, and tail/headwind, the 4500 is the Kestrel Meter of choice for military professionals, HAZMAT teams, and flight crews.
