• Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature

• Precise: detects the smallest air velocities from as little as 0.1 m/s – ideal for laminar flow measurements in cleanrooms

• Convenient: probe with a practical button on the handle for storing individual readings, convenient measurement at ceiling outlets with optional telescope (up to 1 m)

• Intelligent calibration concept
