Perform Safety Compliance Checks or Acoustic Analysis

The Amprobe SM-20A Sound Meter meets the measurement needs of safety engineers, health, industrial and safety offices as well as quality control. Use it to perform compliance checks and acoustic analysis.

It uses two different weighting filters required by the IEC651 and ANSI S1.4 Type 2 for audio filtering. The A weighting is for general noise sound level and the C weighting is for measuring sound level of acoustic material control in various environments (ie 94 dB 1 kHz, etc). The SM-20A also offers a PC interface.
