BTMETER BT-100 Handheld Anemometer Wind Speed & Temperature Meter — Pocketable, Backlit LCD, Tripod Mount

The BTMETER BT-100 is a compact handheld anemometer that measures wind speed, wind temperature, wind chill and estimates air flow (CFM) for HVAC, outdoor sports and drone use.

The BT-100 combines a bright backlit LCD, dual temperature sensors and an 8-vane rotor to provide reliable air-velocity readings in five units and temperature in °C/°F. Lightweight and pocketable, this wind speed gauge fits in a jacket or bag and includes a tripod mount and protective case, making it useful for fieldwork, hobby activities and quick HVAC checks.

How accurate is the BT-100 for measuring wind speed and temperature?

The BT-100 offers precise wind-speed readings from 0.67 to 67.1 mph with a stated accuracy of ±2% of the reading, and temperature from -10 to 60°C (14–113°F) with ±2°C tolerance. Its 8-vane rotor and resolution of 0.1 m/s capture low airflows, while the 0.2°C temperature resolution helps with fine adjustments and calculations.

• Wind speed range: 0.67–67.1 mph (five selectable units: m/s, km/h, ft/min, knots, mph)
• Temperature range: -10–60°C (14–113°F) with °C/°F switchable
• Resolution: 0.1 m/s for velocity; 0.2°C for temperature
• Accuracy: approximately ±2% for wind speed; ±2°C for temperature

How does the BT-100 help with HVAC tasks and CFM calculations?

The BT-100 provides direct wind-speed data that you can combine with duct cross-sectional area to estimate volumetric airflow (CFM). Its sensitivity to low airflows and simple readout make it practical for quick vent checks, balancing, and troubleshooting without heavy instruments.

• Use wind speed (V) and duct area (A) to calculate CFM: Q = V × A
• Sensitive 8-vane rotor picks up low-velocity flows in ducts and vents
• Backlit screen and easy unit switching speed up on-site measurements
• Lightweight case and tripod mount let technicians take steady readings

Can I use the BT-100 while flying drones or for outdoor recreation?

Yes—the BT-100 is designed for field use including drone flights, sailing, kite-flying and photography. The tripod thread and compact footprint let you secure the meter for continuous monitoring while you operate other gear, and the included protective case keeps it ready in a pack or boat bag.

• Metal threaded tripod hole for hands-free, continuous readings
• Portable, pocket-size design with protective carrying case included
• Backlit LCD for visibility during low-light outdoor sessions
• Batteries included so you can start measuring immediately

What features make the BT-100 easy to use and maintain?

The BT-100 focuses on straightforward controls and durability: manual or auto power-off, a low-battery indicator, and a bright backlit display simplify field operation. The unit runs on two AAA batteries and the body is lightweight for repeated handheld use without fatigue.

• Bright backlit LCD with low-battery indicator for reliable reading visibility
• Manual or auto power-off to conserve battery life
• Included 2 × 1.5V AAA batteries to get started right away
• Compact, ergonomic housing that fits in a pocket or tool bag

Who is this for? The BTMETER BT-100 suits HVAC technicians, drone pilots, sailors, outdoor photographers and hobbyists who need a portable, accurate wind speed and temperature meter for routine checks and field measurements. If you want an affordable, easy-to-carry anemometer with tripod mounting and CFM usefulness, the BT-100 delivers simple, reliable data without bulky equipment.
