1.Product introduction of air volume measuring instrument

The air flow meter is also called an air flow meter. The air flow meter is equipped with an integrated impeller wind speed/temperature probe with a diameter of 100mm to measure wind speed, air volume and temperature. The volume flow rate is displayed directly, and the flow rate can be accurately calculated by simply inputting the cross-sectional area of the pipe. You can quickly switch to the current temperature reading. In addition, the direction of air flow can be displayed. The instrument has time period and multi-point average calculation functions to calculate the average values of air volume, wind speed and temperature. Users can choose an air volume hood to help better detect the air volume at the grille outlet and air valve. The instrument can display maximum/minimum values. The current reading can be maintained using the HOLD key.
