63x – Integrated Digital Sound Level Meter

The 63x Series is designed to make workplace noise measurements as quick and simple as possible. The displayed information can be made as simple or comprehensive as required and all measurement parameters are stored simultaneously, so no incorrect measurements can be made. When the unit is calibrated with the CEL-120 calibrator, the calibration dates and times are stored and downloaded to Casella insight software, validating the accuracy of measurements. Average, peak, and octave band measurements are performed at the same time, so only one measurement needs to be made for all workplace noise applications.

Up to 60 hours of audio files can be stored, commonly used for noise source identification. Stored audio can be played back
on the instrument using headphones or downloaded to Casella insight software. For unattended monitoring, event mode (CEL-633) allows trigger levels (dB) to be set, so additional data (e.g. Leq, Lmax) is stored together with the audio file for later play back or analysis, as well as a profile down to 10ms intervals.
