SLM 109

SLM 109 is a Class 1 integrating sound level meter. It complies with the IEC61672 as well as ANSI S 1.4 standards. The instrument features an industrially designed housing and offers a high level of comfort and style.

The SLM 109 has a dynamic range of 100 dB and does not require range selection. It can measure three parameters simultaneously with the A, C, and Z frequency weightings and with Fast, Slow, and Impulse time weightings. The integration time for Leq, Ln and other integral sound quantities can be programmed from 1s to 24 hours.

The SLM 109 is the ideal choice for performing many kinds of noise measurement tasks, for example, in environmental noise, vehicle noise, industrial application, etc – specially where Class 1 accuracy is required.
