Kestrel® 3000 Pocket Weather Meter
Tracks maximum and average wind speeds along with current readings. Displays wind speed in Knots, Meters per Second, Kilometer per Hour, Miles per Hour, Feet per Minute or Beaufort Force. Temperature, wind chill, heat index and dew point temperature can be displayes in °C or °F. Relative humidity is expressed as a percentage. Measuring modes and display units can be changed at any time and all functions are controlled with two buttons. A hard, slip-on ergonomic case protects the display, buttons and impeller.
Accurate readings may be taken beyond these temperature limits by exposing the unit for the minimum time necessary to take and record measurements.

Kestrel® 3500 Pocket Weather Meter
Providing a wealth of weather information, the Kestrel 3500 measures barometric pressure, altitude, temperature, humidity, wind speed, wind chill, dew point, wet bulb, and heat index. Measure current, maximum, and average wind speed in meters per second, kilometers per hour, miles per hour, feet per minute, knots or Beaufort Force. Temperature, wind chill, heat stress and dew point are shown in °C or °F. Relative humidity is displayed as a percentage. Pressure is measured in hPa or inHg. Altitude is displayed in feet or meters. Measurements are shown on a large backlit display. An innovative thermally-adjusted humidity sensor provides stable, accurate measurements even during abrupt condition changes. Other features include a real-time clock, hold function, quick response external thermistor, a high precision pressure sensor and a user-replaceable impeller. Housed in a waterproof body that floats, the meter features a protective cover with sure-grip over molding. Lanyard and battery included.
Accurate readings may be taken beyond these temperature limits by exposing the unit for the minimum time necessary to take and record measurements.
