CEL-63x Series Advanced Occupational and Environmental Sound Level Meters

Occupational Noise Measurement

The CEL-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. 

• Workplace noise assessments according to ISO9612, OSHA 29CFR 1910.95
• Selection of hearing protection
• Calculation of noise exposure
• Ensuring compliance with workplace noise legislation

 Environmental Noise Measurement

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. An environmental noise monitoring kit is available which protects the instrument and microphone from the weather and allows unattended monitoring for up 10 days. 

• Boundary noise assessments
• Noise nuisance complaints
• Measurements according to ISO1996, BS4142
• UK Construction Section 61 notices

 Model Selection

There are 2 models available, per the model selection table (e.g. CEL-632). Select your frequency analysis requirements by adding ‘A’ for broadband, ‘B’ for octave band and ‘C’ for ⅓ octave e.g. CEL-632C. Then add either a 1 or a 2 to denote the accuracy class e.g. CEL-632C1 for Class 1. Each instrument comes complete with a standard kit case, windshield and calibration certificate.

For an instrument kit add /K1 to the instrument part number e.g. CEL-632C1/K1. Instrument kits include the relevant instrument, acoustic calibrator (CEL-120), USB download cable, batteries, calibration certificates and an executive kit case.
