The WindScribe wind and temperature meter uses patented ultrasonic technology to read wind speed, temperature, and wind chill. An ultrasonic wind barrel employs advanced sensors and microprocessor circuitry. The unit calculates wind speed from 0-150 mph, highest positive speed (headwind), lowest negative wind speed (tailwind), and five-second average and running average. Users can select from mph, kilometers per hour, meters per second, feet per second, feet per minute, or knots. It’s accurate within ±3 percent. The device can determine current temperatures from -40 to 150°F, maximum and minimum temperature, and wind chill. The instrument measures temperatures in tenths of a degree and can display temperatures in degrees Celsius. Applications include ventilation shafts, air conditioning conduits, air ducts, chimney flues, and other industrial and construction uses.
