Class 2 Sound Level Meter
SV 973
SV 973 Class 2 Sound Level Meter meets IEC 61672 and comes with a lifetime warranty on the MEMS microphone. Because the external microphone it is constructed of two MEMS microphones, it may detect sounds as high as 141 dB Peak and as low as 25 dB in the presence of low background noise. The SV 973 sound level meter describes its small size and weight. It is perfect for on-the-go use.
What is a Class 2 Sound Level Meter?
The Class 2 Sound Level Meter is a noise measuring device that meets IEC 61672 class 2 standards. It has a microphone, a preamplifier, a signal processor, and a display that displays noise results. The class 2 specification is very similar to the class 1 sound level meter specification, but with different acceptance limits and a different range of operational temperature. Class 2’s acceptance limits are greater than or equal to those of class 1.
