CEL - 63X

The CEL-63x Series of sound level meters are the most versatile of meters available; ideal for both noise at work applications (ISO9612, OSHA) and environmental measurements (BS4142). Ensure compliance with workplace noise legislation with the CEL-633 and to assist with the selection of hearing protection. For environmental noise monitoring, the CEL-633 can be used for boundary noise assessment, noise nuisance complaints or in the construction industry, section 61 notices.

• Ideal for Noise at work and environmental applications<

• Simple operation

• Logging of time history

• Audio recording and voice notes

• Broadband Class 2 mode

Measured Parameters

Broadband: LXY, LXYmax, LXYmin, LXeq, LXpeak, Lavg, LC-LA, LXIeq, LTM3, LTM5, LAE. Workplace dose values are calculated within insight software.

Octaves and ⅓ octaves: LXY, LXeq, LXYmax, 5x Ln% (on CEL-633). Where X is the frequency weighting A, C or Z and Y represents time weighting Fast (F), Slow (S) or Impulse (I). All weightings simultaneously measured where appropriate

CEL-633 model additionally stores 5x Ln values in broadband and octave modes. For time history data, all parameters are logged for period times plus 6 selectable profile parameters (plus 5x Ln values on CEL-633). Memory Memory: 2GB (>1 year logging when set to 1 second interval, 999 runs). All parameters stored and accessible via Casella insight. Total measurement runs: 999. Events: 999 events/run. 10 hours of audio recording in high quality mode, 60 hours in low quality mode. For long term unattended monitoring the CEL-630 takes a new run daily for up to a total of 400 days

Audio Recording
