 Noise Monitoring Station with Remote Control
With a Noise Monitoring Station from NTi Audio, both short-term sound level measurements and long-term monitoring can be easily achieved. At the core is an XL2 Sound Level Meter, which in turn connects to the Internet via a NetBox. The remote access to the monitoring station is directly via the NTi Audio Gateway or the self-managing NoiseScout Web Portal.
The XL2 Sound Level Meter is the ideal instrument for professional noise measurements. The NetBox serves as an interface for the control of the XL2 and the remote access to the measured data. The monitoring station is connected to the Internet via 3G, LAN or Wi-Fi. The Class 1 XL2 Sound Level Meter is up and running at the push of a button.

XL2 Sound Level Meter Calibration according to IEC61672 
NTi Audio offers calibration services for its devices in addition to the broad range of audio, acoustic and vibration measurement solutions. Besides the calibration of individual system components, the sound level meter calibration according to IEC61672-3:2013 is now available for the XL2. The specified procedures for periodic sound level meter testing are followed and a comprehensive calibration certificate is presented.
Standards are an integral component of professional measurement technology. They ensure uniform, comparable, reproducible and documented quality. IEC61672-3 deals with "procedures for periodic testing of time-weighting and integrating sound level meters" and is an internationally recognized standard. The current version, from 2013, describes both acoustic measurements, such as noise and frequency, as well as a variety of electrical tests. During the sound level meter calibration the detailed parameters of the XL2 are recorded and compared with the limits specified in the standard.
