The WM-4 is a complete weather station in your hand

The Ambient Weather WM-4 is a comprehensive handheld wind meter, directional compass, comfort index monitor and psychrometer, all in one compact, portable, rugged package. The WM-4 measures wind speed, wind direction, temperature, relative humidity and compass direction, and calculates wind gust, dew point, wet bulb and dry bulb temperature, Delta T, wind chill and comfort index.

USA-made Fluxgate Compass

The WM-4 has a USA-made fluxgate compass for precise digital wind direction measurement, and it can also be used to calculate crosswind & head/tail wind readings with the built in wind vane. Unlike traditional compasses which require leveling, the WM-4 reads when held vertically and can be used to take a bearing on a distant landmark or reference location.

Jack Knife Case Design

The jack knife case design protects the unit, and allows you to hold the case while taking precise temperature measurements, avoiding false readings from your hand temperature.

Abundant Applications

Applications include backpacking and hiking, biathlon, camping, climbing and mountaineering, athletic trainers, golfing and caddying, hang gliding, kite boarding, kite surfing, model airplanes, paddle sports, sailing and yachting, scuba diving, ski patrol, sky diving, snow making, snow sports, wind surfing, forestry and firefighting, amateur weather watching, meteorology, NOAA weather data collection, storm chasing, skywarn spotters, TV weather reporting, wind power generation, construction, HVAC, shooting sports, motor sports, scientific and educational research. The WM-4 can be tripod-mounted and accessories include a wind tunnel for very accurate directional measurements, replacement impeller, soft belt carrying case, and humidity calibration kits to insure the humidity is within specified range.Special Notes and Caveats: The LCD display will not operate below approximately 14 °F. Use the warmth of your body or environment for use in cold weather conditions. The temperature sensor is inside the monitor, takes several minutes to stabilize, and is influenced by body heat and direct sunlight.Specifications:Wind speed range: .8-89 mphWind speed accuracy: ±3% when aligned with winds axisCurrent wind response time: 1-secondAverage wind response time: over 10 secondsMaximum wind response time: 1-secondCross wind head/tail wind response time: 5 secondsWind direction response time: 1 secondTemperature range: -20° to +158°FTemperature accuracy: ±1.8°FTemperature response time: 1 minuteDew point range: -20° to +158°FDew point accuracy: ±3.6°FDew point response time: 1 minuteWet bulb accuracy: ±3.6°FWet bulb range: 32° to 100°FWet bulb response time: 1-minuteWind chill range: -50° to +50°FWind chill accuracy: ±1.8°FWind chill response time: 1 secondRelative humidity range: 5-95%Relative humidity accuracy: ±3%Relative humidity response time: 1 minuteDelta T response time: 1-minuteCompass accuracy: ±2°Compass range: 0 to 360Compass response time: 1 second
