Sound level meters

The Rion NL series of sound level meters are designed to conduct a range of measurements, including spot checks around areas of potentially high noise levels such as production plants, construction areas and air conditioning.

The easy-to-operate instruments can be customised for a variety of uses such as a Class 2 sound level meter with statistical capabilities or a Class 1 real-time 1/3-octave analyser.

The series includes five models - NL20, NL21, NL22, NL31 and NL32 - each providing a range of measurements and features including: Lmax, Lmin, Leq, Lp and L1-L99 measurements; data storage to compact flash; optional logging kit; solar panel; and remote connectivity. The series also feature upgradeable program cards, enabling live audio recording, real-time 1/3-octave analysis and FFT analysis.
