Bluetooth Vane Anemometer WT87B WINTACT
Wind speed measurement: 0.3–30 m/s |
Temperature range: -10°C to +45°C | Bluetooth + USB communication

The WT87B is a compact and precise vane anemometer with a built-in Bluetooth module, designed for measuring air flow speed, temperature, and indicators such as Windchill or the Beaufort scale. The device allows connection to a smartphone or computer for data recording, analysis, and archiving.

The use of an 8-blade rotor and a high-quality sensor ensures measurement accuracy and reliability in various environmental conditions.

Applications of the anemometer:

• Measurement of air flow in ventilation and air-conditioning systems

• Environmental condition assessment indoors and outdoors

• Monitoring the operation of industrial chimneys and exhaust outlets

• Useful for outdoor sports enthusiasts

Device functions:

• Measurement of air speed in 5 units: m/s, km/h, knots, ft/min, mph

• Measurement of air temperature: °C / °F

• Beaufort scale — 12-level wind speed classification

• Windchill — information on the cooling effect of wind

• Bluetooth — data transfer capability to a mobile app

• Backlit display — readability in darkness

• HOLD function — freeze the current measurement

• Auto-off — battery saving

• Battery level indicator

Mobile app and PC software:

• Real-time measurement analysis (charts)

• History and export of data to .xls files

• Settings for units, measurement interval, and air parameters

• Compatibility: Android 5.0 and above
