AOPUTTRIVER Pro HVAC Anemometer CFM Air Flow Meter — Detachable Vane Probe, Backlit Display

Engineered for technicians and facility managers, this compact instrument combines a detachable vane probe, large backlit display, and memory functions to speed routine airflow checks. It converts measured velocity into volumetric flow once you enter duct area, offers multiple units for wind speed, and stores hundreds of measurements so you can work without returning to a laptop. Robust accuracy and a long battery runtime make it practical for job-site use in cramped ducts and mechanical rooms.

How does this anemometer measure air flow in ducts?

The meter reads velocity with the detachable vane probe and converts that velocity into CFM or CMM after you input the duct’s cross-sectional area. This lets you quickly quantify supply and return airflow without separate calculations. Readings update on the large LCD so you can verify measurements at the grille.

• Enter duct cross-section between 0.001 and 9999 to compute CFM/CMM automatically.
• Vane probe reports wind speed up to 45 m/s (100 mph).
• Velocity units: m/s, km/h, ft/min, knots, mph for flexible reporting.

What accuracy and ranges can I expect for wind speed and volume?

This meter is built for professional HVAC ranges: high top-end speed and fine volumetric resolution. Accuracy supports reliable field decisions during balancing, commissioning, or troubleshooting air distribution problems.

• Wind speed up to 100 mph with ±3% + 0.2 resolution accuracy.
• Airflow reporting up to 999,900 CFM/CMM with 0.001 resolution.
• Onboard temperature sensor reads from 32°F to 113°F for density context.

How does the detachable extendable vane probe improve field work?

The probe separates from the host unit and is mounted on an extendable handle with a flexible coiled cable, enabling access to deep or awkward duct locations. This design keeps the display in easy view while the sensor reaches into vents, speeding measurements and improving safety.

• Detachable vane permits remote placement in ducts and grilles.
• Extendable handle and coiled cable fit confined or high-access spaces.
• Handheld host shows real-time readings while probe is positioned remotely.

What data and power features help during long jobs?

Onboard memory, a backlit screen, and power-saving features reduce downtime and data re-entry. Store hundreds of groups, review them on-site, and rely on extended battery life for multi-task field sessions without frequent replacements.

• Stores up to 600 measurement groups with recall and MAX/MIN/AVG functions.
• Large backlit LCD for visibility in dim equipment rooms and ducts.
• Auto power-off and efficient circuitry yield about 20 hours continuous from a 9V battery.

Who is this for: HVAC contractors, building commissioning teams, facility maintenance staff, and industrial technicians who need a portable, accurate airflow meter for balancing ventilation, verifying unit performance, or diagnosing airflow issues. It’s suitable for professionals who require reliable CFM/CMM conversion, a flexible probe for tight spaces, and in-field data logging without extra software.
