Kestrel 5500FW Fire Weather Pro with Compass, LiNK and Vane Mount
5500FW Fire Weather Meter Pro Safety
What's new with the Kestrel 5500FW over the StandardKestrel 5500:
- PIG Screen (Probability of Ignition)
- FDFM (Fine Dead Fuel Moisture)
Note the PIG Screen will show FDFM at the bottom.
Advantage over the Kestrel 3000 & Kestrel 3500FW models: You won't need to calibrate this meter! NK/Kestrel stand by this and other 5000 series models to hold calibration within drift for 5 years.
Replacing a Sling Psychrometer with a Kestrel is a huge step in time saving and accuracy. Some have struggled to take this leap and we wrote this quick Kestrel vs. Sling article that may answer questions of accuracy.
Calibration:
- Kestrel will stand by the RH for 5 years, and will adjust it within that 5 years if needed.
- Kestrel will repair, recalibrate or replace any defective product within the warranty period. “Defective” includes measurements outside of our accuracy spec plus stated drift.
- RH (Relative Humidity): See Chart for more detail.
- Accuracy: +/- 2%RH
- Sensors: 10 to 90% 25°C non-condensing
- Calibration Drift: Typically less than +/- 0.25% per year!
- 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.
