XL3 Acoustic Analyzer NTI AUDIO

The Swiss NTi Audio XL3 is a high-performance, intelligent acoustic analyzer that operates as smoothly as a smartphone on the touch screen (with the help of buttons) and is mainly used for noise measurement, reverberation time testing, building acoustics testing and room acoustics testing. The newly launchedChinese system ofthe instrument makes the testmore intuitive and convenient fordomestic users; XL3 supports full networking, and any mobile device can remotely control and access data. The optimized system also supports OneDrive remote file push service. All saved new measurement data will be pushed to your OneDrive folder in real time, so you can view and process the data without wiring or visiting XL3.

I. XL3 Acoustic Analyzer NTI AUDIO Standard Configuration Description:

The standard configuration of NTi Audio XL3 acoustic analyzer mainly includes XL3 host +M2340 class 1 microphone and other accessories such as lithium battery, data cable, power adapter, instrument box and so on. The XL3 acoustic analyzer is equipped as standard for all sound pressure level measurements, spectral noise analysis (octave and 1/3 octave) and simple T20 or T30 method measurements of octave reverberation times from 63 Hz to 8 kHz.

XL3 Acoustic Analyzer NTI AUDIO Product Features:
1. Suitable for high-precision noise measurement, spectrum analysis, indoor acoustics and architectural acoustics testing;
2. Advanced CPU, sensor and display technology, compact and rugged body wrapped in high-performance hardware;
3.4.3 inch high-resolution IPS color touch screen, theme optional, can clearly display sound pressure level data;
4. Common operations can still be directly accessed through physical buttons, XL3 switch machine, measurement start and end are very convenient;
5. Data sampling rates up to 96 kHz, frequency range 0.3 Hz - 45 kHz, XL3 instruments can even carry out infrared and ultrasonic measurements;
6. Scales capacity to several terabytes by choosing SD card or external SSD storage;
7. USB Type C interface facilitates connection, audio files can also be recorded and saved;
8.XL3 Sound pressure level optimized for integration into noise monitoring systems—— Data can be transmitted to a computer in binary format;
9.XL3 integrates web page and file server, which can be accessed through the built-in wired or wireless function of the instrument, and all measurement data can be downloaded without interrupting the measurement;
10. To record meteorological data, the instrument can also be connected to mobile weather stations;
11.XL3 device time synchronization through ntp protocol online, this feature combined with optional API interface, can control the access of instrument data at any time, greatly simplifying the difficulty of instrument integration into the entire monitoring system.
