GN302 Digital Anemometer — Portable Wind Speed, Air Flow, Altitude and Barometric Pressure Tester Key benefits Multi-function measurement in one handheld meter: measures wind speed, air flow (volume), altitude and barometric pressure with digital readout and averaging capability to reduce fluctuations. Solves common field and shop problems: quickly verify HVAC airflow, confirm outdoor wind conditions, and monitor pressure/altitude changes without switching instruments. Portable and easy to use: designed for on-the-go testing so technicians and field users can get reliable data at the point of measurement. Primary features Model: GN302 digital anemometer / air flow tester meter. Functions: wind speed, average air volume (air flow), altitude, and barometric pressure readings. Digital averaging: smooths transient variations for clearer, repeatable results during spot checks and short-term measurements. Portable tester meter: compact, handheld form factor for field or site use. Why customers need it Reduces uncertainty: a single device that captures multiple environmental and airflow parameters eliminates guesswork and decreases the need to carry several tools. Saves time: fast digital readouts and averaging let you complete inspections and adjustments more efficiently. Increases confidence in decisions: measure wind and pressure conditions that affect HVAC balancing, ventilation, outdoor work, and environmental monitoring. Practical applications HVAC and building maintenance: verify supply and return air flow, troubleshoot ventilation issues, and confirm system performance during servicing. Outdoor and site work: measure wind speed and air movement for construction planning, safety checks, or short-term site assessments. Environmental and field checks: monitor barometric pressure and altitude-related conditions for field experiments, surveys, or portable diagnostics. What to expect in use Handheld operation for quick spot checks and portable monitoring. Digital readouts with averaging for more stable, actionable numbers. One tool that covers wind speed, air flow/volume, altitude and barometric pressure measurements. Who it’s for HVAC technicians, building engineers, field technicians, environmental technicians, and anyone needing a compact, multi-parameter anemometer for portable measurements.
