Reliable air speed measurement at a reasonable price.

Perfect for use in HVAC, environmental studies, hazardous spill clean ups, electrostatic precipitators, and all types of air flow measurements. Based on the principle that a freely turning turbine will rotate at a speed directly proportional to the wind speed. One piece construction with built-in probe. Select readout in any of 5 scales: meters/second (0.4–30), feet per minute (80–5900), miles per hour (0.9–68), knots (0.8–58), or kilometers per hour (1.4–108). Simultaneously displays temperature in °C or °F. Advanced features include RS232 output, continuous moving average, min/max/avg, auto power off, and hold functions.
