Air-flow Measuring Instrument with New MC20 Display and Control Unit

MC20 with sensors (left to right) Micro, Mini, Mini-Steel, Macro, HygroAir20

Hand-held Measuring Instrument for Air-flow, Humidity and Temperature

The MiniAir®20 is a:

  • Vane anemometer
  • Hygrometer
  • Thermometer

and serves to measure flow velocity of gaseous and liquid media, relative humidity and temperature. It features high precision and robustness and is especially suitable for mobile and laboratory applications.

  • All MiniAir20 vane measuring sensors can be connected
  • Automatic sensor detection
  • Very simple operation, handy keyboard
  • Easy to repair on site thanks to the snap-on head principle
  • Momentary value measurement
  • All three channels can be displayed simultaneously
  • Accuracy: +1.0 % f.e. +1.5% f.m. (for MiniAir20 Mini)
  • Interval measurement
  • Average, minimum and maximum values can be displayed simultaneously
  • Volume measurement (flow measurement)
  • Storage on microSD card
  • IR interface for on-site report printer
  • Battery operation, mains operation possible
