Kestrel® 3500 Pocket Weather Meter

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 overmolding. Lanyard and battery included.
