BTMETER Handheld Anemometer BT-100WM — Portable Multifunction Wind Meter with Backlit Display & Data Logging

The BTMETER BT-100WM is a pocket-sized multifunction anemometer that gives fast, accurate wind speed, temperature, humidity, pressure and altitude readings for outdoor and HVAC use.

The BT-100WM combines a compact handheld design with a clear backlit display and data-logging features so you can monitor changing conditions on the trail, at the range, onboard a boat, or while testing airflow. It measures wind speed, wind chill, relative humidity, dew point, barometric pressure and elevation, and stores barometric readings for later comparison. Built-in convenience features like unit selection, max/min/avg modes, auto shutoff and a tripod mount make it versatile for both casual and professional tasks.

How does this anemometer measure wind and weather accurately?

The BT-100WM uses a precision impeller sensor and calibrated internal sensors to report wind speed, temperature and atmospheric pressure within tight tolerances. Readouts update quickly so you can capture gusts or steady flows, and resolution is fine enough for detailed HVAC or shooting adjustments.

• Wind speed range: 0.67–67.1 mph with ±5% accuracy
• Temperature range: -10 to 45°C (14–113°F), ±2° accuracy
• Barometric pressure logging: stores 16 data groups for comparison
• Altitude measurement up to 19,685 ft with selectable units

What display and modes help me capture useful readings in the field?

The backlit LCD shows current, max, min and average wind speeds alongside temperature and humidity values. You can switch units quickly between mph, m/s, km/h, ft/min and knots, making it easy to use across sports, scientific or industrial contexts.

• Multiple display modes: Current, Max, Min, Average
• Unit options for wind, temperature, pressure and altitude
• LCD backlight for low-light or night operations
• Low-battery indicator and automatic shutdown to save power

Can I record data and mount the meter for steady monitoring?

Yes — the BT-100WM can log barometric pressure readings for later analysis and includes a tripod mounting hole for hands-free or long-duration measurements. That makes it useful for weather observation, HVAC flow testing and long-range shooting adjustments.

• Logs up to 16 barometric pressure groups for trend comparison
• Tripod-compatible threaded mount for stable readings
• Pocket-sized and lightweight for transport to field sites
• Useful for drone piloting, sailing, hunting, kite flying and airflow tests

Who is this for? The BTMETER BT-100WM suits outdoor enthusiasts, technicians and hobbyists who need a reliable, portable weather and airflow meter. If you do tactical shooting, sailing, drone work, HVAC diagnostics or general weather observation and want precise, logged readings with flexible unit options and a durable handheld form factor, this device covers those needs without being bulky.
