Key Features<\/div>\n

Key Features<\/h2>\n

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.<\/p>\n <\/div>\n

\n
\n

High-Sensitivity Wind Wheel Sensor<\/h3>\n

The wind wheel sensor helps detect light airflow and supports wind speed measurement from 0 to 30m\/s with 0.1m\/s resolution.<\/p>\n <\/article>\n

\n

Multiple Unit Switching<\/h3>\n

Switch wind speed units among m\/s, mph, km\/h, ft\/min, and knots. Long press the unit key to switch temperature between \u00b0C and \u00b0F.<\/p>\n <\/article>\n

\n

1.6-Inch Backlit Display<\/h3>\n

The large numerical display and backlight make readings easier to view in dim environments or workshop conditions.<\/p>\n <\/article>\n

\n

Max \/ Min And Data Hold<\/h3>\n

Use Max\/Min mode to track changing airflow readings, or Data Hold to lock the current displayed value for easier recording.<\/p>\n <\/article>\n

\n

5-Minute Auto Power-Off<\/h3>\n

The anemometer automatically powers off after about 5 minutes of no key operation to help save battery power.<\/p>\n <\/article>\n

\n

Wind Chill And Beaufort Scale<\/h3>\n

TR401 displays a 0-12 Beaufort wind force level and can prompt a Wind Chill warning in low-temperature, high-wind conditions.<\/p>\n <\/article>\n <\/div>\n\n
