For Occupational Noise

  Simultaneous measurements of all workplace noise parameters
  Standard setups for workplace noise legislation
  Measures parameters for hearing protection selection by the SNR, HML and octave band method
  Analyse time history of noise levels
  Optional high range microphone, up to 165dB

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 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.

Data Sheet

For Environmental Noise

  Simultaneous broadband and frequency measurement
  Data markers
  Back erase function
  Real-time frequency analysis
  Single measurement range
  Triggered 'event' capture

Data can be marked to signify any significant events, the data from which can be removed afterwards in insight software.

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 analysis, as well as a profiles 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.
