About This

• Pro CFM Anemometer – The BT-846A wind speed meter accurately measures air velocity, airflow, and temp with a wide range and high precision. Wind speed in m/s, km/h, ft/min, knots, mph, air volume in CFM/CMM, and tempe in °C/℉. Measuring range: 0.001–100 mph (±3% accuracy), Tempe: 32–113℉. Supports real-time, Max, Min, 2/3 Max, and AVG readings for professional airflow analysis
• Accurate Airflow Measure – Measures airflow from 0–999,900 ft³/min (CFM/CMM) with resolution 0.001–100, and supports an airflow area setting range of 0.001–9999 ft². Simply set the cross-sectional area of the vent, and the air volume will display in real time for precise airflow balancing and ventilation testing. Plus 600 data storage groups for recording airflow changes
• Separated Extendable Wind Sensor – Equipped with user-friendly wind sensor vane(replaceable), allowing you to view readings easily while testing or balancing air vents, AC units, or dust collection systems. Wind speed gauge have backlit LCD display and auto power-off, Ideal for HVAC troubleshooting, airflow balancing and ventilation system measure
• Range & 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
• Service & Support - The kit comes with a durable carrying case that keeps both instruments protected and neatly organized. The package includes 1× BT-846A Airflow CFM Meter, 1× BT-189B Manometro, and corresponding Accessories. Enjoy responsive 24/7 customer service and lifetime technical support from BTMETER.
