Sound Monitoring System (Sound Level Meter & Noise Dosimeter)
Sound level meter S12 measures and displays the analog noise waveforms numerically. Sound
Pressure Level, Equivalent Continuous Sound Level or Leq, Peak, etc. are displayed in decibels.
Sound pressure 20 (μPa, microwave Pascal) is set as a reference level. It consists of a frontend and
a sensor. It is portable and easy to use.
A noise dosimeter (American English) or noise dosemeter (British English) is a
specialized sound level meter intended specifically to measure the noise exposure of a person
integrated over a period of time; usually to comply with Health and Safety regulations such as
the Occupational Safety and Health (OSHA) 29 CFR 1910.95 Occupational Noise Exposure
Standard or EU Directive 2003/10/EC.
Applications
- Used to measure sound/ Noise level of vehicles, factories, machines, engines, traffic, musical instruments, loud speakers, indoor/ outdoor applications.
- Upto 24 hours recording, Real time display, real time report print, detailed reports save options, powerful PC software for detailed report print.
