With a linearity range of 100dB, level range switching is not required. Compatible with memory cards for saving measurement data.
***Features*** Noise has a nature that changes constantly, which leads to many evaluation methods. The NL-21, equipped with the latest DSP (Digital Signal Processor), simultaneously calculates almost all currently considered evaluation values. To support automatic measurement, auto storage, and data processing via a computer, it adopts a compact flash card. Large amounts of data can be easily stored in memory. Continuous measurement is assured with a wide dynamic range of 100dB. Simultaneous measurement of equivalent noise level Leq, time-weighted noise level LN, maximum values, etc. Long-term data recording is possible on a memory card (compact flash card). An integrated timer function enables long-term automatic measurement. It features a dual measurement function for LAeq and LCpeak. The backlit LCD provides a clear screen display. The comparator output function allows for setting level determination. Functionality can be expanded with program cards for various filter settings and more.
