High-accuracy ESAW ECP-403 Sound Level Meter with real-time SPL display, data logging, octave band filtering, and wide frequency range for labs, industry, and environmental monitoring.The ESAW PCE-430 Class 1 Sound Level Meter is a professional-grade instrument designed for precise sound pressure level (SPL) measurement in compliance with IEC 60651:1979, IEC 60804:2000, IEC 61672-1:2013, ANSI S1.4-1983, and ANSI S1.43-1997 standards. Built for laboratories, environmental agencies, industrial plants, and educational institutions, this portable device delivers accurate noise monitoring across a frequency range of 3 Hz to 20 kHz and a measuring range of 22 … 136 dB(A).
The large illuminated LCD screen displays numerical and graphical SPL readings in real time, while the integrated octave band filtering detects even subtle frequency differences. The built-in data logger records at adjustable intervals (1 second to 24 hours) to a removable micro SD card, with PC data transfer possible via SD card reader or direct USB connection.
With A, B, C, and Z frequency weightings and fast, slow, and impulse time weightings, the PCE-430 ensures compliance with workplace safety regulations, environmental noise laws, and academic research requirements.
