Key Features
TR401 keeps airflow and temperature measurement simple with a sensitive wind wheel sensor, clear display, multiple units, quick reading refresh, automatic shut-off, wind chill warning, and Beaufort wind force reference.
High-Sensitivity Wind Wheel Sensor
The wind wheel sensor helps detect light airflow and supports wind speed measurement from 0 to 30m/s with 0.1m/s resolution.
Multiple Unit Switching
Switch wind speed units among m/s, mph, km/h, ft/min, and knots. Long press the unit key to switch temperature between °C and °F.
1.6-Inch Backlit Display
The large numerical display and backlight make readings easier to view in dim environments or workshop conditions.
Max / Min And Data Hold
Use Max/Min mode to track changing airflow readings, or Data Hold to lock the current displayed value for easier recording.
5-Minute Auto Power-Off
The anemometer automatically powers off after about 5 minutes of no key operation to help save battery power.
Wind Chill And Beaufort Scale
TR401 displays a 0-12 Beaufort wind force level and can prompt a Wind Chill warning in low-temperature, high-wind conditions.

Questions And Answers
These answers cover TR401 measurement functions, units, batteries, Wind Chill warning, display controls, auto-off, package contents, related instruments, and warranty support.
TR401 measures wind speed, air temperature, Beaufort wind force level, and wind chill warning conditions. It is suitable for airflow and temperature checks such as automotive AC outlets, ventilation systems, outdoor use, fan manufacturing, maritime operations, and wind energy applications.
TR401 supports wind speed units m/s, mph, km/h, ft/min, and knots. It supports temperature units °C and °F. Press the Unit key to switch wind speed units, and long press the Unit key to switch temperature units.
TR401 uses 3 AAA 1.5V alkaline batteries. Insert the batteries according to the positive and negative marks inside the battery compartment. Replace them promptly when the low-battery icon appears, and remove the batteries before long-term storage.
The Wind Chill warning appears when the temperature is below 0°C and the wind speed is greater than 5m/s. When the WINDCHILL signal appears, pay attention to low-temperature and high-wind conditions.
Press the power/backlight key during operation to turn the backlight on or off. Press the Data Hold key to lock or unlock the current displayed reading. Press the measurement mode key to switch among real-time, Max, and Min reading modes.
Yes. During normal operation, TR401 automatically turns off after approximately 5 minutes of no key operation to save power. Auto power-off can be disabled from the power-off state by using the key combination described in the user manual.
No. TR401 is designed for wind speed and temperature measurement. For illuminance, choose TE301. For sound level, choose TN201. For temperature and humidity, choose TM101. TR401 is not a pressure tester or refrigerant leak detector.
