Informationen zur Produktgruppe

XL2 Akustisches Analysegerät

Eine einzigartige Kombination aus einem modernen Schallpegel-Messgerät, umfassenden akustischen Analysegerät und einer leistungsfähigen Audio-Analysefunktion.

Das akustische Analysegerät misst den Schallpegel, das Echtzeitspektrum für 1/3 Oktave, FFT, RT60-Nachhallzeit, Verzögerung, Polarität, STI-PA-Sprachverständlichkeit (optional)
Die Audio-Analysefunktion misst den Effektivwert des Pegels, THD und Frequenz
Flexible Benutzerschnittstelle mit personalisierten Anwendungsprofilen
Das Schallpegelmessgerät erfüllt die internationalen Standards für Umgebungsgeräusche (DIN15905-5 DE/SLV 2007 CH) einschließlich der erforderlichen Korrekturwerte
Sprachanmerkungen für protokollierte Messungen
Erzeugt 48 V dc Phantomspannung und bietet automatische Mikrofonerkennung
Mini-SD-Karte, herausnehmbar
Integrierte Echtzeituhr
Aufladbare, austauschbare LiPo-Batterie
M4260-Mikrofon muss getrennt bestellt werden
