• norm-compliant

Select one of the numerous measuring programs. The measurement data assistant guides you step by step through the measurement process.

Examples - how the measurement assistant supports you in

• IAQ measurement according to EN12599:
  Configuration: Input of duct geometry, apertures and measurement points, calculation of measurement depths
  Measurement: Graphically guided measurement with all relevant measurement points
  Result: Statement of volume flow and the exact measurement inaccuracy
• PMV/PPD measurement in accordance with EN ISO 7730:
  Configuration: Determination of clothing index and activity
  Measurement: Parallel measurement of ambient and radiated temperatures, flow velocity and relative humidity
  Result: Statement as a PMV/PPD curve including evaluation
• Turbulence measurement according to DIN EN 7730:
  Configuration: Allocation of probes to measurement positions
  Measurement:Simultaneous measurement at three heights according to norm
  Result: Statement of measurement values at all heights as a value, table and graph.
