Hand-held measurement device for air-flow
The portable measuring instrument MiniAir Junior is the appropriate device to measure flow velocity of gaseous media.This portable instrument combines high precision and easy manipulation. Therefore it is ideal for mobile control and measuring applications.
The vane anemometer MiniAir Junior is suitable for measuring the velocity of gaseous media. The measured velocity with a vane anemometer is considered the most accurate of the available methods. Vane speed and velocity are practically linear and largely independent of pressure, temperature, density and humidity.
The MiniAir Junior is especially well suited to measurements in the heating, air conditioning and ventilation sector.
