Logging Environmental 1/3 Octave Band Class 1 SLM – CEL-633C1

The CEL-633C1 is a 1/3 Octave Band Sound Level Type I Meter ideal for testing Occupational and Environmental Noise.

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.

For environmental noise 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.

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