AMF115A and AMF115B Digital Anemometers | Wind Speed Meter

HANDHELD ANEMOMETERS FOR AIR VELOCITY AND TEMPERATURE

AMF115A and AMF115B Digital Anemometers

The AMF115A and AMF115B are handheld digital anemometers for measuring air velocity and air temperature. Both models provide multiple wind-speed units, temperature conversion between Celsius and Fahrenheit, and common reading modes for field measurements. The AMF115B adds air-volume measurement, computer communication, Bluetooth connectivity, and data-recording features.

The impeller sits at the top of the instrument, so the vane can be held directly in the air stream while the readings are taken. The LCD and the keypad are on the front face, and both models run on a single 9 V battery.

Key Features

Air velocity	Measurement up to 30 m/s with selectable units: m/s, ft/min, knots, km/h, and mph
Air temperature	Measurement from −10 °C to 45 °C, with °C/°F selection
Reading modes	Real-time, maximum, minimum, and average wind-speed readings, plus data hold
Display and power	Beaufort wind scale, wind-chill indicator, low-battery indicator, display lighting, and automatic shutdown after 10 minutes without button operation
AMF115B additions	Air-volume measurement, USB communication with computer software, Bluetooth connection to a mobile app, and recording, review, and export functions
