Voltcraft AN-80 Anemometer 0.3 to 30 m/s Wind Speed Air Temperature CFM

HVAC technicians, facility managers, and field engineers often need quick, reliable airflow and temperature readings in ducts, vents, and open spaces. The Voltcraft AN-80 anemometer delivers exactly that: a compact vane instrument that measures wind speed from a gentle 0.3 m/s up to 30 m/s, air temperature from -10 to +50 °C, and calculates air volume in CFM or CMM. Its backlit LCD shows current, maximum, minimum, and average values, while the data hold function freezes readings for easy recording. Powered by a single 9V battery and supplied with a protective carrying case, this meter is ready for on-site diagnostics, commissioning, or routine maintenance.

• Backlit LCD with low battery indicator
• Power: 1x 9V block battery (included)
• Operating conditions: 0 to 50 °C, 0 to 80% RH non-condensing
• Sensor type: vane / impeller
• Included accessories: 9V battery, carrying case, instruction manual

Why choose it

The AN-80 combines essential HVAC measurement functions in one rugged handheld tool. Its wide speed range and multiple unit options suit both low-velocity indoor airflow checks and higher outdoor wind measurements. The average function is particularly useful for traversing ducts to obtain a representative reading, while the CFM/CMM calculation saves time when sizing or balancing ventilation systems. The backlit display remains readable in dim mechanical rooms, and the auto power off preserves battery life during long workdays.

Ideal use cases

• HVAC system commissioning and balancing
• Ventilation duct airflow verification
• Indoor air quality assessments
• Field service and maintenance checks
• Environmental monitoring and wind speed logging

Good to know

The vane sensor is protected by a robust housing, but avoid exposing the unit to condensing humidity or temperatures outside the specified operating range. For accurate CFM readings, enter the duct cross-sectional area as described in the manual. The included carrying case keeps the meter and battery safe during transport, and the 9V battery is pre-installed for immediate use.
