BTMETER Hot Wire Anemometer Dual Port Manometer Kit - 12 Selectable Units

Key features

• Industrial Hot-Wire Airflow Meter - BT-9000F thermal anemometer features a high-sensitivity hot-wire probe that detects even subtle airflow changes. Measures wind speed (0.2–67 MPH / 0.1–30 m/s) with ±5 % ± 1 digit accuracy, and supports five units (m/s, km/h, ft/min, knots, mph). Tempe range: 32~113 ℉ (°C/℉ switchable). Ideal for HVAC diagnostics, duct inspections and airflow analysis
• Telescopic Probe & Flexible Design - CFM Meter with The extendable probe rod (extends 11~38 inch) with a 68-inch cable easily reaches ducts, vents, and confined spaces. The 360° rotatable and bendable sensor head adapts to any angle, making it perfect for measuring in high, narrow, or hard-to-reach areas such as
• Smart CFM/CMM Measurement - No manual calculation needed—just set the duct’s cross-sectional area, and the airflow value appears instantly. Measures 0–999,900 CFM/CMM/CMS with area units (㎡ / ft²) adjustable between 0.001–9999. Simplifies HVAC airflow balancing, system testing, and ventilation efficiency verification
• Wide Range & High Accuracy - Pro Gas Pressure Gauge could measure ±13.79 kPa / ±2.000Psi (Limit max pressure: 30.00 psi) with ±0.3%FS high accuracy. ±0.25%FS repeatability and 0.001 resolution. 11 gas measurement units optional, including mmHg, inHg, ftH₂O, cmH₂O, KPa, Mbar, Bar, Psi, Kgcm², inH₂O, and Ozin². Over-range indication available
• Data Record & Zero-out - Equipped with two 3.18mm tube connectors, the BT-189B digital manometer accurately measures static (positive/negative) and differential gas pressure in HVAC systems. Press"REC" button to record and review max / min / average air pressure data; Short-press "HOLD” button to freeze measurement data and Long-press 5 seconds to clear out remaining data to ensure measure accuracy
• Complete Kit with Carrying Case: The kit comes with a durable carrying case that keeps both instruments protected and neatly organized. The package includes 1 BT-9000F Airflow CFM meter, 1 BT-189B Differential Pressure Gauge and corresponding accessories with lifetime technical support from BTMETER
