Comfort measurement with the multi-function measuring instrument testo 480
PMV/PPD measurement according to ISO 7730
Step by step through the measurement The testo 480 calculates norm-compliant PMV/PPD values from ambient/radiant temperature, air humidity, flow velocity and clothing, among others. It then guides you through the measurement step by step and displays the results as a table and/or graph.
Suitable probes and accessories for PMV/PPD measurement:
Turbulence measurement in accordance with EN 13779
Step by step through the measurement In cases of complaints about draughts, you can carry out a degree of turbulence measurement or a draught risk measurement with the testo 480 and the comfort probe. After the measurement, the measurement protocol shows the norm-compliantly measured mean flow velocity, the mean temperature as well as the degree of turbulence and the draught rate calculated from these.
