MS6708-digital sound level meter
1.This soundlevel meter complies with IEC651 type 2 and ANSI S1.4 type2
2.With themeasuring scope from 30 to 130 dB and automatic shifting function.
3.A and Cweighting network selection.
4.High speed(FAST)/Low speed (SLOW) response rate selection.
5.Maximum(MAX) locking function.
6.Digitaldisplay, good anti-interference performance power saving.
7.With thebacklight feature, it is appropriate for gathering the sound data at night. Tosave power, backlight auto power off function is provided.
8.Compositematerial injection molding process isadopted for casing with anti -drop structure design. It is not only extremelywear-resisting, but also elegant.
9.With powersaving and high-reliability circuit design, well designed high-efficiency powersupply circuit makes the batteries moredurable.
