The Kestrel 5400FW Fire Weather Meter offers all the same measurements and capabilities as the standard Kestrel 5400 Heat Stress Tracker, making it ideal for athletic, occupational, and heat safety monitoring — while also providing powerful additional tools specifically for wildland firefighting.
Just like the 5400, the 5400FW measures and reports temperature, humidity, wind speed, and WBGT (Wet Bulb Globe Temperature) for accurate heat stress and environmental monitoring in sports, military, and industrial settings.
In addition, the 5400FW includes advanced fire-weather features such as Fine Dead Fuel Moisture (FDFM) and Probability of Ignition (PIG) — critical indices used by wildland firefighters to evaluate ignition risk and fire behavior potential in the field.
In short, the Kestrel 5400FW does everything the 5400 does — and more. It’s the perfect choice for anyone who needs reliable heat stress tracking and the added capability to assess fire weather conditions.

Awesome customer service!!
The 5400 provides a more accurate reading than other WGBT units at a reasonable price. It is easy to use and calibrate.

Greatest service ever!
The equipment are in new and good condition. The shipping are really fast after making a payment, they send a package in next day. I am ordering product from Thailand. To be honest after comparing price, Extreme meter LLC is the best price in product and shipping fee.

Urgent need for my K2 winter expedition.
I needed urgent for my K2 winter expedition. I was on the last min and needed the goods to be sent in Iceland. Their chat online worked 100% and I was able to add on one extra peace even after I checkout. They send with UPS same day and I had the package 3 days later here in Iceland. Extreme Meters works and has good service I recommend them.

Couldn't be more pleased
I ordered the Kestrel 3550FW meter. Received email notifications reporting the progression of my order up to delivery, which was much quicker than I'd expected. Couldn't be more pleased with the product and service.

The service was prompt and cordial.
The service was prompt and cordial. The Kestrel is used to measure wind velocity and temperature when applying pesticides for agriculture crop production. It is also used to measure weather conditions for livestock comfort.
