Logging Environmental Octave Band SLM Class 1 Kit

The CEL-633B1 is a 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 fromwhich can be removed afterwards in insight software.Up to 60 hours of audio files can be stored, commonly used for noisesource identification. Stored audio can be played back on the instrumentusing 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 insightsoftware.
Octaves: LXY, LXeq, LXYmax, 5x Ln% (on CEL-633).Where X is the frequency weighting A, C or Z and Y represents timeweighting Fast (F), Slow (S) or Impulse (I). All weightings simultaneouslymeasured where appropriate.
CEL-633 model additionally stores 5x Ln values in broadbandand octave modes.
For time history data, all parameters are logged for period times plus 6selectable profile parameters (plus 5x Ln values on CEL-633).

CEL-633B1-K1 is a kitincluding the relevant instrument,acoustic calibrator (CEL-120), USB download cable, batteries,calibration certificates and an executivekit case.
