BT-9100A Wireless Bluetooth Thermal Anemometer Extendable Multi-Angle Probe Wind Speed, Airflow & Temperature Measurement APP Data Chart Analysis Smart Temperature, Humidity & Airflow Meter HVAC Testing Instrument

Product Overview
The 9100A is a professional wind speed, airflow and temperature measurement instrument integrating wireless Bluetooth transmission, smart app control and high-precision thermosensitive sensing. Equipped with an extendable multi-angle probe reaching up to 650mm, it supports five-step adjustment from 0° to 180°, effortlessly handling complex scenarios such as ducts, vents and confined spaces. Via the dedicated ‘Intelligent Meter’ app, users can view real-time data curves, save historical records, and set alarm thresholds, making it an ideal smart tool for HVAC, environmental monitoring, industrial ventilation, and scientific research/education.

Core Feature Highlights
Wireless Bluetooth connectivity: Stable transmission within 10-15 metres, with real-time display of wind speed/airflow/temperature data via the app

Extendable Multi-Angle Probe: 320mm–650mm length with 0°, 45°, 90°, 135°, and 180° angle locking for comprehensive coverage
APP Data Visualisation: Real-time curves, peak recording, data export (Excel format), share via WeChat/email/cloud storage
Triple-Precision Measurement: Wind speed (0-40m/s), airflow (CFM/CMM), air temperature (-10~50℃). Thermistor sensors deliver rapid response and high accuracy.
Intelligent Settings: Configurable sampling rate, customisable auto-shutdown timer, wind speed/temperature threshold alarms.
Long-Lasting Type-C Charging: Integrated 800mAh lithium battery provides 6-7 hours of operation on a full charge.
Sensor protective cover: Pull down to expose sensor during measurement, push up to shield afterwards for extended lifespan
Multi-unit conversion: Wind speed supports m/s, ft/min, Knots, Km/h, Mph; Airflow supports CFM, CMS, CMM
