PCE-325 Class II Sound Level Meter
PCE-325 Class II Sound Level Meter
The PCE-325 Class II Sound Level Meter is a device used to measure sound levels in various environments, commonly in noise pollution studies, workplace monitoring, and general acoustic measurements. It's classified as a Class II instrument according to international standards, which means it provides a moderate level of precision suitable for many professional but non-critical applications.
This meter typically features capabilities such as the ability to measure sound levels in decibels (dB), A and C frequency weighting to mimic human hearing sensitivity at different frequencies, and time weighting (fast and slow) to capture varying sound levels. It often includes a digital display, data logging features, and sometimes connectivity options like USB or Bluetooth for data transfer.
