Frequency Analyzers

N-131 & N-132 Sound Level Meters

The Nor130 Series of Sound Level Meters are designed and manufactured to the latest sound level meter standards and comprises two products. The Nor131 is a Class 1 (precision) instrument whilst the Nor132 is designed in accordance with the less accurate Class 2 requirements. Both meters offer the same features with exception of the detachable preamplifier which is only available on the Nor131 version.

SC-310 Integrating sound level meter, real time 3rd octive band spectrum analyser, and real time room noise analyser.

The SC-310 is a powerful and easy to use instrument. It can work as an integrating sound level meter type 1. It is also a real time spectrum analyser in one-third octave band and octave band, with Class 1 filters. In addition options allow measurement of reverberation time (T60) using interrupted noise or impulse excitation with view of decay curve. Completes HC levels in real-time.

SC-30 · Integrating-averaging sound level meter and spectrum analyser

The SC-30 is a type 1, easy to use, integrating sound level meter that allows you to make sound measurements quickly, con-veniently and easily. It has a single range, so there is no need to make any previous range adjustments.
