Pro digital Sound Level Meter MASTECH MS6708


This is a professional Sound Level Meter, it can measure the ambient sound level, such as sound level around factories, workshops, schools, residential, offices, road, audio etc. It also can be appropriate for noise engineering, product quality control, health prevention and treatment, etc.  

Functionals: 
- This sound level meter complies with IEC651 Type 2 and ANSI S1.4 Type 2. 
- With the measuring scope from 30 to 130 dB and automatic shifting function 
- A and C weighting network selection 
- High speed (FAST)/Low speed (SLOW) response rate selection
- Maximum (MAX) locking function 
- Digital display, good anti-interference performance, power saving 
- With the backlight feature, it is appropriate for gathering the sound data at night. To save power, backlight auto power off function is provided. 
- Composite material injection molding process is adopted for casing with anti-drop structure design. It is not only extremely wear-resisting, but also elegant. 
- With power saving and high-reliability circuit design, well-designed high-efficiency power supply circuit makes the batteries more durable.
