Fire Weather Chief Pro Kit Overview
Fire Chief Pro Kit contains two (2) Kestrel 5500FW Fire Weather Meters Pro with LiNK and one (1) DROP D3FW Datalogger. The 5500FW meter is an all-in-one hand-held belt weather kit replacement, containing every critical weather measurement including PIG and FDFM. The DROP D3FW data logger can be left onsite for continuous recording of conditions and trends which can then be viewed on a mobile device and shared via email. Measure, log, track trends and expand capabilities with this kit on the free Kestrel LiNK App.
Kestrel 5500FW Fire Weather Meter Pro with LiNK
The fast and easy tool for taking weather observations, the Kestrel 5500FW Fire Weather Meter Pro provides NIST-traceable accuracy, reliability and usability when it matters most. Measure every environmental condition plus PIG and FDFM and view trends with on-screen data graphing. Drop-proof, dust-proof, waterproof and able to withstand extreme environments without damage, your Kestrel Fire Weather meter can stand up to the abuses of work on a fire line wherever you’re assigned. Measures wind speed (anemometer) and direction, temperature (thermometer), humidity (hygrometer), water vapor content of the atmosphere (psychrometer), plus 10 other meterological paramenter.
Kestrel DROP D3FW Datalogger
Each Kestrel Fire Weather DROP measures just 1 x 1.8 x 2.4 inches (24 x 46 mm x 60 mm) and weighs just 1.2 ounces (34 grams). DROP loggers meet military and international standards for water, dust and shock resistance (IP-67 and MIL-STD-810G) and are conveniently equipped with a sturdy D-ring for hanging wherever needed. The DROP D3FW measures: Dew Point Temperature, Heat Stress Index, Pressure Trend, Relative Humidity, Station Pressure (Absolute Pressure), Temperature, Wet Bulb Temperature.

Connectivity
Kestrel LiNK for iOS & Android
The Kestrel LiNK® App for iOS/Android allows you to Wirelessly connect with iOS and Android devices and remotely view real-time environmental data and receive alerts for changing conditions. Available for your Kestrel 5 Series Meter or DROP Logger, Kestrel LiNK also provides easy transfer of the Kestrel’s stored data log, a clear graph of all historical data. Alerts can be customized based on temperature, heat index, wind, or other measurements. LiNK enables easy firmware updates of Kestrel 5 series meters.
Data is transmitted wirelessly via Bluetooth® Low Energy within wireless range (100’ line of sight– reduced by walls and obstructions). Mobile device and Kestrel must remain within range to trigger alerts.

Startup speed stated as lower limit, readings may be taken down to 0.4 m/s |79 ft min|1.5 km/h |.9 mph |.8 kt after impeller startup. Off-axis accuracy -1% @ 5º off axis; -2% @ 10º; -3% @ 15º. Calibration drift < 1% after 100 hours use at 16 MPH|7 m/s. Replacement impeller (NK PN-0801) field installs without tools (US Patent 5,783,753). Wind speed calibration and testing should be done with triangle on impeller located at the top front face of the Kestrel. Measuring wind speeds above 60 m/s / 134.2 mph can damage the impeller |
| Ambient Temperature | 0.9 °F 0.5 °C | 0.1 °F 0.1 °C | -20.0 to 158.0 °F -29.0 to 70.0 °C | Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. For greatest accuracy, avoid direct sunlight on the temperature sensor and prolonged sunlight exposure to the unit in low airflow conditions. Calibration drift is negligible for the life of the product. For further details, see Display & Battery Operational Temperature Limits. |
| Relative Humidity | 2%RH | 0.1 %RH | 10 to 90% 25°C noncondensing | To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift is typically less than ±0.25% per year. |
| Pressure | 1.5 hPa|mbar 0.044 inHg 0.022 PSI | 0.1 hPa|mbar 0.01 inHg 0.01 PSI | 25°C/77°F 700-1100 hPa|mbar 20.67-32.48 inHg 10.15-15.95 PSI | Monolithic silicon piezo-resistive pressure sensor with second-order temperature correction. Between 1100–1600 mbar, unit will operate with reduced accuracy. Sensor may not operate above 1600 mbar and can be damaged above 6,000 mbar or below 10 mbar. Calibration drift is negligible for the life of the product. |
| Compass | 5° | 1° 1/16th Cardinal Scale | 0 to 360° | 2-axis solid-state magneto-resistive sensor mounted perpendicular to unit plane. Accuracy of sensor dependent upon unit’s vertical position. Self-calibration routine eliminates magnetic error from batteries or unit and must be run after every full power- down (battery removal or change). Readout indicates direction to which the back of the unit is pointed when held in a vertical orientation. Declination/variation adjustable for True North readout. |
