The XPT801 Class 1 integrating sound level meter and spectrum analyzer is the entry-level model of the Expert range, developed to offer an optimised price-performance ratio while remaining fully professional. It is designed for acoustic technicians looking for a reliable, upgradeable instrument suitable for the most common applications, including environmental noise, occupational noise assessment and a wide range of industrial and laboratory inspections.
Compared to the top-of-the-range XPT800, this Class 1 sound level meter follows the same scalable platform philosophy, with a 4.3” colour touch screen display, compact design and advanced connectivity, but offers a lighter set of functions focused on the most common operating requirements. The XPT801 is therefore a very interesting technical solution for users looking for a modern and complete instrument with a more streamlined approach compared to the flagship model.
From a metrological point of view, the XPT801 sound level meter complies with IEC 61672:2013 and offers a dynamic range exceeding 120 dB. It supports interchangeable microphones with automatic identification through the Sensor Digital Interface, measures the main broadband parameters and performs real-time octave and one-third octave analysis according to IEC 61260-1:2014, with a technical configuration well aligned to professional monitoring and verification activities.
This model also integrates advanced field functions including continuous or trigger-based audio recording, spectral masks, overload management and automatic event identification. These features are particularly useful for unattended monitoring campaigns and all activities where a more structured documentation of the acoustic phenomenon is required beyond a simple overall level measurement.
In terms of connectivity, the XPT801 includes Wi-Fi, 4G, LAN, USB-C and RS232/485 for data transfer and remote control. The 4 GB internal eMMC memory, with microSD support, allows measurement campaigns and time histories to be archived using logic designed for monitoring and technical reporting. Integration with NS Storage is also available for more fluid and modern data management.
The internal rechargeable battery with intelligent power management supports more than 24 hours of continuous measurement campaigns. This makes the sound level meter particularly useful for daily monitoring activities, environmental surveys and professional field measurements in industrial environments.
If the XPT800 is the model to choose when the most advanced functions and maximum expandability are required, the XPT801 is the professional integrating sound level meter and spectrum analyzer for users looking for a streamlined solution with an excellent balance between performance, technical equipment and investment.
