Our Review of the Kestrel 4200 Pocket Air Flow Tracker
![]() |
All Kestrel Pocket Weather Meters are made in the USA and covered by a 5-year warranty against manufacturing defects. Additionally, every single Kestrel manufactured is calibrated for every single value, either directly against NIST-traceable standards or against an intermediary standard that is calibrated daily. Every unit is shipped with a FREE Certificate of Conformity that states what calibrations were performed, and the certified performance specifications. |
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 entire Kestrel 4000 series is now available with Bluetooth Technology for wireless communication.
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.
Additional features of the Kestrel 4200 with Bluetooth Technology:
- Communicate with your Kestrel 4200 at a range of up to 30-feet
- Maximize the battery life of your meter
- 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.
- It is no longer necessary to purchase an interface separately, the new Kestrel Meters with Bluetooth include the software necessary to communicate wirelessly.
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.
