GVDA GD150 Digital Anemometer

GVDA GD150 Digital Anemometer – Handheld Wind Speed Meter with Beaufort Scale & Three-Color Backlight

The GVDA GD150 is a professional digital anemometer designed for accurate wind speed measurement across a wide range of applications. Featuring a precision vane sensor with bearing, 6 selectable wind speed units (m/s, km/h, ft/s, ft/m, knots, mile/h), Beaufort scale indicator (0-12), and a three-color backlight display for quick wind force assessment, this portable meter is ideal for wind energy, meteorology, industry, agriculture, environmental protection, highways, airports, and marine applications. The data hold, MAX measurement, and auto power-off functions ensure convenient and reliable operation.

Key Features:

• 1) Wide Air Velocity Range – 0.70 to 30.00 m/s with 0.01 m/s resolution for precise measurements
• 2) 6 Selectable Units – m/s, km/h, ft/s, ft/m, knots, mile/h – switchable for global compatibility
• 3) Beaufort Scale Display – 0-12 scale for quick wind force assessment without unit conversion
• 4) Three-Color Backlight – Green (0-4 Bft), Orange (5-7 Bft), Red (8+ Bft) – instant visual wind strength indication
• 5) Fast Sampling Rate – One reading per 0.5 seconds for responsive, real-time monitoring
• 6) Data Hold Function – Freeze current readings for convenient recording and analysis
• 7) MAX Measurement – Long press to capture and display maximum wind speed reading
• 8) Auto Power Off – Automatically shuts down after 10 minutes of inactivity to preserve battery
• 9) Low Battery Indication – Clear warning when battery replacement is needed
• 10) Portable & Lightweight – Compact size (155×50×26mm, 171g package weight) with included gift box

Air Velocity Units & Ranges:

Three-Color Backlight Indicator:

• Green Backlight: 0-4 Beaufort scale – light wind conditions
• Orange Backlight: 5-7 Beaufort scale – moderate to strong wind
• Red Backlight: 8 Beaufort scale or higher – strong to gale force wind

How to Use:

1. Press the POWER button to turn on the device
2. Hold the anemometer with the fan plane aligned vertically to the wind direction
3. The display shows wind speed, Beaufort scale, and unit simultaneously
4. Press UNIT key to select desired wind speed unit (m/s, km/h, mile/h, ft/m, ft/s, knots)
5. Press HOLD to freeze the current reading; press again to return to normal mode
6. Long press MAX button (>1 sec) to activate maximum value function; press again to return to normal mode

Where It Can Be Used:

• Wind energy & meteorology – monitor wind conditions for turbines and weather stations
• Industrial & agricultural – ventilation system testing, spray monitoring, crop drying
• Environmental protection – air quality and pollution dispersion studies
• Highways, airports & ports – wind safety monitoring for vehicles, aircraft, and ships
• Hydrology & water conservancy – wind speed measurement on reservoirs and coastal areas
• Outdoor sports – sailing, windsurfing, kite flying, drone flying

Maintenance & Precautions:

• Batteries not included – requires 2 × 1.5V AAA batteries
• Do not touch the fan blade with force – may damage the sensor
• Do not store or operate in areas with high temperature or humidity beyond specified limits
• Avoid strong light directly shining on the fan to prevent measurement errors
• Clean the housing regularly with mild detergent and damp cloth – do not use corrosive agents or solvents
• Replace batteries when low battery symbol appears – open battery cover and insert new batteries according to polarity markings

Package Includes:

• 1 × GVDA GD150 Digital Anemometer
• 1 × User Manual
• 1 × Gift Box

Note: 2 × AAA batteries are not included.
