Mobile vane anemometer for air-flow, humidity, temperature
MiniAir20

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

  • 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

You can choose among the following Air-flow sensors:

  • Micro (Ø 11 x 15 mm)
  • Mini (Ø 22 x 28 mm)
  • Macro (Ø 85 x 80 mm)

The starter kit for air-flow measurement consists of:

  • MiniAir20 Mini air-flow measurement sensor
  • MC20 evaluation unit
  • Carrying case
  • Power supply unit and connecting cable
  • Carrying case

You can add to the contents of the case when required:

  • other MiniAir20 Micro and Macro air-flow measurement sensors
  • HygroAir20 humidity measurement sensor
  • Mobile printer
  • Telescopic bars
  • Handle for HygroAir20 with extension rod
  • Spare snap-on heads

Technical data

MiniAir ® 20 with MiniController MC20

The frequency of rotation is almost proportional to the air-flow velocity and largely independent of pressure, temperature, density and humidity.

The MiniController MC20 converts the rotational frequency into a standard signal and shows the measured value in the display.

All measured values can also be saved simultaneously and printed out on site.
