Five units for air velocity measurement supported: m/s, km/h, ft/min, knots, mph Temperature unit option: C or F Measurement options for air velocity: Max, Average, and Current values Anemometer function: Air velocity and temperature measurement in a single device Benefits and practical use International unit flexibility: switch among common air velocity units to match regional standards or project requirements without changing hardware. Comprehensive velocity data: view current airflow speed as well as historical context with max and average values for performance assessment and trend analysis. Dual parameter measurement: measure both air velocity and temperature with one instrument, reducing the need for separate sensors. Simple operation: straightforward unit selection and measurement display enable quick air flow checks in various environments. Use scenarios HVAC and ductwork balancing: verify airflow rates in air handling ducts using preferred units and monitor temperature alongside velocity to ensure system efficiency. Outdoor wind monitoring: assess wind speed for construction safety, site planning, or outdoor equipment operation by switching to the most convenient unit. Laboratory airflow testing: perform controlled experiments that require both velocity and temperature readings, and compare current measurements with historical averages.
