CFM Wind Meter Hot Wire Anemometer HVAC, Dryer Vent,AP-9000F Air Flow Meter

Key features

• Professional Hot-Wire Sensor for HVAC ProsBuilt with a high-sensitivity hot-wire sensor, the AOPUTTRIVER AP-9000F detects airflow as low as 0.1 m/s (0.2 mph) with ±5% accuracy. Perfect for HVAC technicians checking vent performance, dryer vent airflow, lab fume hoods, and low-flow drafts that standard vane anemometers often miss.
• Wind Speed, Temp & CFM in One DeviceNo need for multiple tools. This handheld thermal anemometer measures wind speed, air temperature, and air volume simultaneously. Enter the duct area, and the screen displays CFM/CMM instantly — ideal for HVAC balancing, ventilation checks, and confined space airflow verification.
• 10mm Retractable Probe for Tight SpacesThe slim 10mm probe with blade-free design reaches deep into narrow ducts, pipes, and behind equipment where larger vane meters cannot fit. Retractable structure protects the sensor during storage and transport, extending the tool's lifespan.
• Type-C Rechargeable BatteryBuilt-in 1000mAh lithium battery provides extended field use and recharges quickly via included Type-C cable. Adjustable auto power-off and battery-level display prevent unexpected shutdowns.
• Direct Airflow CalculationInput duct cross-sectional area (0.001-9999) to display CFM/CMM airflow directly—no manual calculation needed. Essential for HVAC balancing, industrial ventilation, and air quality assessment.
