BTMETER BT-100 Handheld Anemometer Digital Wind Speed & CFM Meter — Black, Backlit LCD & Tripod Mount

The BTMETER BT-100 is a compact handheld anemometer that measures wind speed, wind temperature, wind chill and estimates airflow (CFM) for HVAC, drones and outdoor activities.

The BT-100 combines a clear backlit LCD, precise 8-vane sensor and dual temperature sensors in a pocketable meter designed for technicians, hobbyists and outdoor enthusiasts. It displays wind speed in five units, reports temperature in °C/°F, and includes a tripod mounting thread for hands-free monitoring. Rugged enough for fieldwork yet lightweight for carrying, the BT-100 aims to make airflow checks, duct measurements and wind assessments fast and repeatable.

How accurate and sensitive is the BT-100 for HVAC and duct testing?

The BT-100 offers a wide wind speed range (0.67–67.1 mph) with ±2% reading accuracy and fine resolution for low flows. Dual temperature sensors and an 8-vane rotor help it pick up small air movements common in vents and diffusers.

• Wind speed accuracy: ±2% of reading, resolution 0.1 m/s
• Temperature range: -10–60°C (14–113°F), ±2°C; resolution 0.2°C
• CFM estimation: wind speed × duct cross-sectional area for quick airflow checks
• 8-vane rotor and two temperature probes improve low-flow sensitivity

What features help when I need hands-free or extended measurements?

BT-100 includes a standard metal tripod thread so you can mount the meter for continuous logging or long exposures. The backlit display and auto/manual power-off extend usability in dim conditions and conserve battery life during fieldwork.

• 1/4" metal tripod threaded hole for mounting on tripods or rigs
• Backlit LCD for visibility in low light
• Manual or auto power-off to preserve batteries
• Lightweight, pocket-size design for easy transport

Which units and readouts does the BT-100 provide for practical use?

The BT-100 displays wind speed in five commonly used units and lets you switch temperature scales between Celsius and Fahrenheit. The clear numeric readout and wind chill function make it useful for weather checks, drone flights and outdoor sports planning.

• Wind speed units: m/s, km/h, ft/min, knots, mph
• Temperature: °C/°F selectable, plus wind chill calculation
• Low-battery indicator so you won’t lose readings unexpectedly
• Simple single-button controls for quick unit switching and power

Who is this for? Technicians performing HVAC commissioning, contractors checking duct CFM, drone pilots needing reliable wind data, and outdoor hobbyists who want a rugged, accurate anemometer. The BT-100 is built for anyone who needs repeatable airflow and temperature readings in a portable tool that can also be mounted for unattended monitoring.
