Hot Wire Anemometer, CFM Meter Wind Speed Gauge, HVAC Air Flow Tester

Key features

• 3-in-1 High-Precision Hot Wire Anemometer – Accurately measures wind speed (0.1–30 m/s, ±5%, with 5 unit options), air temperature (32–113℉ / 0–45℃, ±1.0℃), and airflow (0–999,900 CFM/CMM) in one compact tool. The sensitive hot‑wire sensor captures even the slightest air movements that vane meters miss – essential for HVAC diagnostics, duct testing, ventilation balancing, and environmental monitoring.
• Retractable Probe for Tight Spaces – The telescopic probe extends to reach narrow openings (e.g., ducts, vents, grilles, and behind machinery) with a slim size of just 11.75" × 1.61" × 0.93". Slide down the protective cover to expose the sensor during measurement, and slide it back up to shield against dust and damage when stored. The waterproof and dustproof housing ensures dependable performance on demanding job sites.
• Large Color LCD with Full Data View – The big color screen clearly displays wind speed (real‑time, maximum, and minimum), airflow, and temperature simultaneously – no need to toggle between modes. The adjustable backlight guarantees clear visibility even in dark attics or basements, so you can read all key metrics at a glance.
• Long-Lasting Rechargeable Battery – Powered by a built‑in 1000mAh lithium battery (fully charged in 2‑3 hours via TYPE‑C), this anemometer outlasts disposable batteries while saving you money and reducing waste. The low‑battery indicator keeps you informed, and the settable auto‑shutdown (approx. 5 minutes) extends runtime for all‑day outdoor fieldwork.
• Smart Controls & Instant Unit Conversion – No complex menus – just intuitive buttons. Instantly switch between 5 wind speed units and 2 air volume units (CFM, CMM); toggle ℃/℉ with one press. Enter duct area (0.001–9999) for direct CFM/CMM results. Freeze readings with one‑button data hold, and track fluctuations with Max/Min/Real‑time modes. The 7 slip‑resistant buttons work perfectly with gloves, and the hot‑wire probe plugs into the host for quick setup – ready to measure in seconds.

Professional Hot Wire Anemometer – Handheld Thermal Anemometer for HVAC Air Flow & CFM Measurement The PR-9000F is a professional-grade hot wire anemometer designed for HVAC technicians, field workers, and environmental engineers. Whether you're diagnosing duct airflow, balancing ventilation systems, or monitoring environmental conditions, this portable digital anemometer delivers precise readings for wind speed, air temperature, and air volume. Traditional vane and cup anemometers rely on spinning fans or cups with moving parts – when airflow is too low, the fan may not spin, and dust can cause inaccurate readings. The PR-9000F uses hot wire sensor technology with no moving parts, detects airflow from as low as 0.1 m/s, responds instantly, works in any direction, and requires no regular maintenance. What You Can Measure Wind Speed: 0.1-30 m/s, supports 5 units (m/s, km/h, ft/min, knots, MPH), accuracy ±5% Air Temperature: 32-113℉ / 0-45℃, accuracy ±1.0℃ Air Volume: 0-999,900 CFM or CMM, with adjustable area setting (0.001-9999) Key Features Retractable Probe: Telescopic handle reaches narrow ducts, tight vents, behind machinery. Protective cover keeps sensor safe. Probe: 11.7
