Created for Professionals. Simple for Everyone.
The XL3 is NTi Audio’s modern professional acoustic measurement platform. It combines a sound level meter, spectrum analyzer, reverberation time analyzer, sound insulation analyzer and STIPA analyzer into one field-ready instrument. Its workflow is designed for everyday sound measurements as well as advanced consulting tasks.
Noise Measurement
Measure SPL, Leq, Lmin, Lmax, Lpeak, exposure levels, time histories, spectra and logged sound level data for professional noise assessment.
Room Acoustics
Measure reverberation time and room acoustic parameters for auditoriums, classrooms, halls, conference rooms, studios and public spaces.
Building Acoustics
Use optional sound insulation workflows for airborne, impact and facade sound insulation measurement directly on the instrument.
What Makes XL3 Different?
Single-Range Measurement
The XL3 is designed to simplify field work by avoiding unnecessary range switching. This helps reduce the risk of measurement mistakes when site conditions change unexpectedly.
Networked Workflow
Built-in web and file server access allows remote control and data download through standard browsers over Wi-Fi or LAN. This is especially useful for building acoustics and long-term monitoring.
Open Data Storage
Measurement data is stored on a removable 32 GB microSD card in open TXT format, with support for WAV audio and PNG screenshots for documentation.
High-Resolution Interface
The 4.3″ IPS colour touch display with 480 × 800 resolution gives large, readable measurement values, while physical buttons keep operation practical on site.
Scalable Options
Add options such as Extended Noise Measurement, Sound Insulation, STIPA or Extended Room Acoustics based on your actual application.
Professional Ecosystem
The XL3 works with NTi Audio measurement microphones, weather protection kits, heavy-duty outdoor cases, MeasurEye, Data Explorer and reporting software.
Core Applications
XL3 is not just a meter. It is a configurable acoustic measurement platform for consultants, project teams and institutions that need repeatable, defensible measurements.

Built for Field Work, Built for Collaboration
The XL3 can be operated directly from its touch display and physical keypad, or remotely through a browser. This is useful when the instrument must remain in one room while the operator controls a source or observes a measurement from another location.
- Browser-based remote access via Wi-Fi or LAN
- Integrated web server and file server
- Measurement data download without stopping an ongoing measurement
- NTP support for consistent time stamps across devices
- USB-C connectivity and expandable storage options
