The Kestrel 3000HS will give you accurate Heat Stress measurements, on-site and real-time

Our most popular Kestrel and the Preferred tool of the Wildland Firefighter. The Kestrel 3000 & 3000HS are the go-to tools for monitoring field conditions. You know you’re working hard. Make sure you’re staying safe. This multi-job tool isn't just for firefighters but is used by college and pro athletic trainers where heat stress is an important concern. As a bonus, the 3000HS comes with a copy of the Kestrel Heat Index Reference Guide. Like all of our Kestrel Instruments, they are made in the USA, extremely durable and backed by a full 5 year factory warranty. All Kestrel Instruments are waterproof, drop-proof and they float.

Environmental Measures:

Multiple uses:

  • Highly recommended equipment for wildland firefighters whose lives literally depend on the accurate weather data their Kestrel 3000HS provides.
  • Real-time environmental monitoring keeps you from working past your limits.
  • From the accurate relative humidity readings, the Kestrel 3000 also calculates dewpoint and heat stress index —important information to know when working or playing outdoors in hot and humid conditions.
  • Used by NFL trainers to determine how frequently the athletes need to hydrate, and when the conditions are unhealthy for strenuous exercise.
  • Calculates wind chill. A useful measurement for monitoring athletic teams or workers in cold environments.

Very easy to use, excellent and accurate data, very handy measurements to have. Also very nice working with the company, easy to order and arrived very quickly! So glad I got one, weather measurements are way easier now!

Sensor Specifications

 Wind Speed

Units of Measure: mph | kt | B | m/s | ft/min / km/h 
Specification Range:
  • 0.6 to 40.0 m/s
  • 118 to 7,874 ft/min
  • 2.2 to 144.0 km/h
  • 1.3 to 89.5 mph
  • 1.2 to 77.8 knots
  • 0 to 12 B*
  • 2-131.2 F/S*
Operational Range:
  • 0.6 to 60.0 m/s
  • 118 to 11,811 ft/min
  • 2.2 to 216.0 km/h
  • 1.3 to 134.2 mph
  • 1.2 to 116.6 knots
  • 0 to 12 B*
  • 2-196.9 F/S*
Resolution:
  • 0.1 m/s
  • 1 ft/min
  • 0.1 km/h
  • 0.1 mph
  • 0.1 knots
  • 1 B
Accuracy (+/-): Larger of 3% of reading, least significant digit or 20 ft/min
Notes: 1 inch|25 mm diameter impeller with precision axle and low-friction Zytel® bearings. 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 (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. *F/S only in Ballistics units. Beaufort not available in Ballistics units.

Ambient Temperature:

Units of Measure: Fahrenheit, Celsius
Specification Range:
  • -20.0 to 158.0 °F
  • -29.0 to 70.0 °C
Operational Range:
  • 14.0.0 to 131.0 °F
  • -10.0 to 55.0 °C
Resolution:
  • 0.1 °F
  • 0.1 °C
Accuracy (+/-):
  • 0.9 °F
  • 0.5 °C
Notes: Hermetically sealed, precision thermistor mounted externally and thermally isolated (US Patent 5,939,645) for rapid response. Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. Calibration drift negligible. Thermistor may also be used to measure temperature of water or snow by submerging thermistor portion into material -- remove impeller prior to taking submerged measurements and ensure humidity sensor membrane is free of liquid water prior to taking humidity-based measurements after submersion.

Relative Humidity:

Units of Measure: %
Specification Range: 5 to 95% 25°C non-condensing
Operational Range: 0 to 100% 
Resolution: 0.1 %RH
Accuracy (+/-): 3%RH
Notes: 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.
