Testo 425 Air Velocity Meter is a multi-functional device that records the flow speed, calculates the volumetric flow and also measures the temperature. It has a measuring range of 0 to +20 m/s, making it best suited to low airflow velocity. It features a telescopic flow probe that can be extended to a length of up to 820 mm and has a probe head diameter of 7.5 mm. When you input the duct surface area value, it automatically calculates the volumetric flow during the flow measurement. Single and multi-point averaging features provides the value of average volumetric flow, flow speed, and temperature reading. This Air velocity meter has a Hold button, that helps you to freeze the current reading to compare it with another value, for example. If you forget to switch off the air velocity meter, the Auto-off function will automatically switch off the device which conserves your battery life.
Features of Testo Air Velocity Meter:
