Click2Contact

The Rion NL-52 sound level meter is suitable for measuring environmental noise, noise at work and noise nuisance. The meter becomes a broadband data logger for baseline surveys and compliance monitoring with the NX-42EX option that comes standard on a supplied SD card.

The NX-42RT option also comes as part of the rent from TechRentals, allowing octave and one-third octave band analysis to be performed. NC curve graph display and NC value calculation/display are also possible, assisting workers in the construction industry.

With the help function and manual accessible on the device, there is no need for a paper manual to carry around, allowing users to assist themselves.

The NL-52 features simultaneously recording of both instantaneous SPL and equivalent continuous SPL with the auto-store function, a continuous data output function and a comparator function. The unit is IP54 rated against sprays of water with the exception of the microphone.
