HCS Sound Level Meter

The Sound Level Meter has been designed to meet the measurement requirements for Industrial safety offices and sound quality control in various environments.

Sound Level Meter Features:

  • Ranges from 35dB to 130dB at frequencies between 31.5Hz and 8KHz
  • Display with 0.1dB steps on a 4 digit LCD
  • With two weighting A and C
  • Both AC and DC signals output is available from a single standard 3.5mm coaxial socket suitable for a frequency analyzer, level recorder, FFT analyzer, graphic recorder, etc.
