CFM Anemometer Handheld Air Flow Meter, Kethvoz Digital HVAC Wind Speed Gauge Measuring Airflow Windspeed Velocity Temperature w/MAX/MIN/AVG, Data Record, Industrial Anometer KE 846A

☑️【High Accuracy】The Air Velocity Tester is designed with pro low friction bearing, which can test wind sensitively. Wind Speed Range: 0.3~45m/s(+/- 3%+0.1 reading, Resolution: 0.01m/s). Display in 5 units: m/s, km/h, ft/min, knots, mph. Wind Temperature: 0~45℃ (Fahrenheit & Celsius switchable). ☑️【Pro Airflow CFM Meter】Wind flow range: CFM 0-999900 ft3/min (Resolution: 0.001-100). Air flow area : 0.001-9999 ft2. You can just set the cross sectional area of the register or vent, the air volume will display in CFM/ CMM synchronously during the air flowing measurement. Suitable for HVAC installation and air conditioning system maintenance. ☑️【Data Hold & Record】The professional Wind Guage measure air velocity in 5 measurement modes: Maximum, Minimum, (2/3) Max, Average, and Real-time. It also supports one-click data freeze and 600 groups measurement data storage for further analysis. It is an ideal tool for HVAC professionals. ☑️【Split Type Wind Meter】The extension cord of the wind velocity sensors can be extended up to 2 m, and the telescopic rod can be adjusted up to 5 cm. It is convenient to monitor home ventilation / HVAC system over head and test the workshop dust collection system in the woodworking. Additionally, the 1.69 x 2.36 inch Backlit LCD display helps you read the data easily. ☑️【Multifunctional HVAC tool】Built-in low battery indicator reminds you to replace the battery in time. The Industrial Wind Velocity Sensor will automatically shut down after 5 minutes of inactivity or when the wind wheel is stationary, thereby extending battery life.
