The XL2-TA sound level meter has received Class 1 type-approval from the Physikalisch-Technische Bundesanstalt (PTB) in Germany. The XL2-TA in combination with the M2230 measurement microphone, is officially listed as a type-approved Class 1 sound level meter. The XL2-TA is suitable for environmental noise, occupational health, and sound insulation applications where the measurements require certification.
Receipt of the type-approval certificate confirms the XL2-TA (in combination with the M2230 measurement microphone and the ASD cable) offers full compliance with the Class 1 sound level meter requirements in accordance with the International Electrotechnical Commission (IEC) standards 61672 and 61260 and meets the American National Standards Institute (ANSI) S1.4 Type 1 performance. The XL2-TA offers certified spectral measurements in octave and third-octave resolution, which further comply with Class 0 filter specifications.
The M2230 measurement microphone connected to the XL2-TA via the ASD cable configuration enables the user to monitor the level readings on the instrument display while Class 1 measurements are taken.
