CTL 100
Automatic check of sound level meter




The automatic check consists in comparing sound level meter value with level produced by CTL100.

The principle allows to periodically check sound level meter performance, especially the microphone performance which is the sensing element of the instrument.

Technical data
  • Frquency: 1000 Hz 5%
  • Level: 90 dB 1dB
  • Stability: < 0.5 dB
