NTi Audio Receives Class 1 Certification for XL3 Sound Level Meter
The NTi XL3 Sound Level Meter has received type approval from the Physikalisch-Technische Bundesanstalt (PTB) entity in Germany and can therefore be used for precision-grade Class 1 measurements in full compliance with the sound level meter standard IEC 61672:2014. As NTi Audio confirms, this level of certification qualifies the XL3 for legally compliant measurements of environmental noise, occupational noise, and sound insulation tests in Germany and in many other countries around the world.
