Kestrel 5500 Fire Weather Meter Pro

What’s new with the Kestrel 5500FW over the Standard Kestrel 5500:

You’ll get all the features and benefits of the lightweight waterless 5500 Meter with a few added benefits for US$10,00 more.

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.

The Kestrel 5500 Fire Weather Meter Pro

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.

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.
