Data logging RTA sound level meter NTi Audio
IEC 61672, ISO 1996, DIN 15905

The XL2 is a handheld acoustical analyzer paired with a powerful Audio analyzer. The set of functions is ideal for testing, monitoring and logging of factory or machinery noise pollution.

The practical blend of electrical and acoustical functions, combined with computer connectivity through the standard USB interface, positions XL2 to be an indispensable tool for every engineer.

Acoustilyzer Features

Sound Level Meter

In addition to the familiar instantaneous and integrated sound pressure level (SPL) measurements, the repeatable LEQ and LCpeak measurements complete the event monitoring requirements.
The XL2 visualizes the actual audio spectrum (RTA) without interrupting ongoing sound level measurements. All measurement results may be logged to the internal memory for further investigations.

RTA, Real Time Analyzer

The enhanced real time spectrum analyzer (RTA) features high speed measurements with selectable 1/1 and 1/3 octave bandwidth. The RTA simultaneously provides real time single band SPL and LEQ measurements complying with the IEC 60804.
Stored spectra may be averaged or combined by using the available mathematical functions. The “Max-Min” display is particularly helpful for finding dominant room modes and characterization of listening areas.

Zoom FFT

Extremely fast, real-time Zoom FFT with resolutions up to 0.7Hz over the entire frequency range. The ideal tool for visualization of comb filters and narrow band effects. Features detailed cursor readout and data storage.
