XL2-TA sound level meter wins IEC certification

摘要

The XL2-TA sound level meter is the first type approved sound level meter with a certified input keypad for legal noise nuisance assessment. The Physikalisch-Technische Bundesanstalt (PTB) in Germany confirmed that the XL2-TA in combination with the external input keypad meets the requirements of the standard IEC 61672. The input keypad forms an extension for the XL2-TA SLM to monitor environmental noise. Any noise event can be marked during the ongoing measurement and audio files recorded simultaneously. The keypad offers four marker keys for triggering an event recording or categorizing the type of noise during the measurements.
