NL-53 Sound level meter

Request info/price

NL-53 from RION is the ideal device for simple sound level measurements, e.g. in the areas of occupational safety and pollution control.

The device only has three buttons and is therefore very easy to use. Data is saved in open file format, but can also be evaluated in the Norsonic software.

In addition, the NL-53 is the ideal sound level meter for system integrators who want to control the device via their own software (e.g. for noise monitoring as just one of many components within a comprehensive system).

Applications

Noise at Work
Environmental monitoring
Sound power (ISO 374x)

Highlights

Color and touch screen
Very slim case
Full-fledged LAN interface

About

text

The NL-53 is a IEC 61672 Class 1 Integrating Sound Level Meter.

“Connect” is the keyword for RION’s new sound level meter
Newly equipped with LAN terminals, the NL-53 offers various enhanced functions to connect to other communication devices and to maximise the effectiveness of noise measurement tasks. The user interface is designed to be intuitive and easy to understand for the ultimate in user-friendliness.

Simultaneous measurement for up to four channels
Set different frequency weighting and time weighting characteristics for each channel to record instantaneous SPL and calculated values. A single unit can measure up to 4 channels simultaneously, allowing users to reduce their working time.

LAN terminal
By connecting to a network, a remote connection via web browser of PC or smartphone may be established. You can check the status of the unit, view and acquire measurement data, and listen to real-time audio.

USB Type-C connector
Compatible with USB power supply from mobile battery unit. Enables acquisition of measurement data or settings changes via communication commands. PCs can read the SD card inside the sound level meter as a removable disk.
