Digital Sound Level Meter

The MASTECH MS6700 is a digital sound level meter designed to measure environmental noise levels from 30dB to 130dB with a 2dB accuracy. It features a 4-digit LCD display with 0.1 dB resolution, A and C frequency weighting, and fast or slow response selection. The unit includes an analog bar indicator, backlight, auto power-off, and AC/DC auxiliary output for connection to external recording devices. It operates on six AAA batteries, which are not included.

Suited for environmental and industrial checks

This meter suits technicians, engineers, and facility managers who need to verify noise levels in factories, workshops, schools, offices, or traffic zones for compliance or quality control. It also supports data logging with a maximum value hold function, date and time display, and a sampling rate of 2 times per second. Buyers requiring Class 1 precision or real-time frequency analysis without an external analyser should look elsewhere.

30dB to 130dB measurement range

The 30dB to 130dB range determines whether the MS6700 covers the sound pressure levels encountered in your specific application, from quiet offices to loud industrial machinery. The 50dB dynamic range ratio and 31.5Hz to 8kHz frequency response define the instrument's ability to capture relevant noise components across that span. Confirm that these limits match the regulatory or testing standards you must meet.

Questions about this item

What does the A/C frequency weighting selection change in practice?

A-weighting matches human hearing response for environmental noise, while C-weighting captures flatter low-frequency response for machinery or traffic assessment.

What physical socket does the analog output use?

A 3.5 mm ground socket provides both AC and DC auxiliary output for connection to a frequency analyser or XY recorder.

How do you power the meter for the first measurement?

Insert six AAA batteries (not supplied), observe the low-power indicator, then select Fast or Slow response before pressing the MAX hold button.
