Four Cups? Not With Our Anemometer

An anemometer is a device used for measuring wind speed. The term is derived from the Greek word anemos, meaning wind, and is used to describe any air speed measurement instrument used in meteorology oraerodynamics. The first known description of an anemometer was given by Leon Battista Alberti around 1450. The simplest form in common use is the cup anemometer, which catches the wind with rotating cups, usually four. Cup anemometers are still used for wind, power performance evaluations and site calibrations.

An anemometer is also a common instrument used in HVAC. Specifically for indoor air quality and HVAC / R technicians measuring Heat / Ventilation / Air conditioning / Refrigeration wind flow and temperature in residential, commercial and industrial air conditioning systems. Data Centers and other hi-tech manufacturing operations use anemometers to insure that the air flow is sufficient to maintain proper temperature or cleanliness of the facility.

The Sper Scientific Model 840001 Datalogging Anemometer automatically records up to 16,000 data points in the field, along with time and date. This data can later be downloaded to a computer with the included software or logged in real time. The software also enables real time data logging directly from the anemometer to the computer. The microprocessor calculates air volume (CFM) as well as air velocity and min/max and simultaneously displays air temperature in ºC or ºF. Also reads type-K or J thermocouple probes. Features a calendar/clock, auto power off, and hold functions. This well-made anemometer has a detachable probe, fold-out tripod and a large easy to read LCD. Comes ready to use in a protective foam lined carrying case complete with metal vane anemometer probe, software, RS232 computer connection cable, 4 AA batteries, and a 3V button cell battery.
