Ambient Weather WM-4 Handheld Weather Station w/ Windspeed, Direction, Temperature, Humidity, Compass, Dew Point, Heat Index and more

Availability: In stock

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.

It 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.

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.

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.

Includes a 2 year factory warranty from Ambient Weather.
